摘要：
In this paper a Ni/Al layered double hydroxide (LDH) was first synthesized and further immobilized on a carbon ionic liquid electrode (CILE), which was prepared by using 1-(3-chlorine-2-hydroxypropyl)-3-methylimidazolium acetate as the modifier. The characteristics of LDH/CILE were investigated by scanning electron microscopy (SEM) and cyclic voltammetry. Under the selected conditions the LDH/CILE showed better electrochemical response towards the detection of dopamine (DA) than the CILE. The parameters of DA electro-oxidation on the LDH/CILE were calculated with the values of the electron transfer coefficient (α), the number of electrons transferred (n), the apparent heterogeneous electron transfer rate constant (ks) and the diffusion coefficient (D) as 0.426, 2.25, 1.66 s−1 and 7.06 × 10−5 cm2/s, respectively. This modified electrode can be further used to detect DA content in the real drug samples.

摘要：
Zn<inf>2</inf>SnO<inf>4</inf> with novel octahedron structures have been successfully synthesized on a large scale by applying surfactant hexadecyl trimethyl ammonium bromide (CTAB) throughout controllable hydrothermal reaction. X-ray diffraction (XRD), scanning electron microcopy (SEM), transmission electron microscopy (TEM), and high-resolution transmission electron microscopy (HRTEM) were used to characterize the final products. The results have revealed that three-dimensional (3D) Zn<inf>2</inf>SnO<inf>4</inf> octahedrons were assembled with numerous intercrossed hexagon nanoplates with a mean edge length of 300 nm and an average thickness of 50 nm. Based on the time-dependent experimental results, the growth mechanism has been thoroughly investigated. The morphology of as-prepared octahedrons evolved from cubes with branched structures on their surfaces to octahedrons assembled with hexagon nanoplates, indicating that the process of crystal growth was controlled by a crystallization-dissolution-recrystallization growth mechanism. More importantly, we found that CTAB played a key role during the total formation process of as-obtained Zn<inf>2</inf>SnO<inf>4</inf> octahedrons. UV-vis spectroscopy was further employed to estimate the band gap energy of the octahedron microstructures. ©2009 Elsevier B.V. All rights reserved.

摘要：
Large-scale copper nanowall array on the bulk Fe-Co-Ni alloy substrate has been prepared in aqueous solution at room temperature via an electroless deposition method. The thickness of the nanowalls is about 15 nm. A possible growth mechanism of the nanowalls was proposed. The effects of reaction temperature, reaction time and the amount of critical agent (Fe<sup>3+</sup>) on the morphology and crystalline phase of the nanowalls were investigated. Furthermore, the electrochemical performance of Sn film supported on the as-prepared copper nanowalls current collector is enhanced in comparison with that on the commercial copper foil when used as anode for Li-ion batteries with the operating voltage window of 0.01-2.0 V (vs. Li). After 20 cycles, the discharge capacity AR of Sn-Cu nanowalls anode still remained 365.9 mAh g <sup>- 1</sup>, that is, 40% retention of the reversible capacity AR, while the initial charge capacity AR of Sn film cast on commercial Cu foil was 590 mAh g<sup>- 1</sup>, dropping rapidly to 260 mAh g<sup>- 1</sup> only after 10 cycles. ©2010 Elsevier B.V.

摘要：
We have developed a general two-step synthesis of large-scale arrays of one-dimensional (ID) nanostructured Co3O4 directly on various substrates. Throughout a controllable hydrothermal process using urea as mineralizer and hereafter with a postcalcination process under air atmosphere, Co3O4 ID nanostructure arrays have been grown firmly on insulating substrates, such as glass slides and ceramics, which is quite convenient for the construction of gas sensor devices without any extra electrode preparation process. Furthermore, this direct-growth approach can be readily extended to conductive substrates (ITO, Ti, Fe-Co-Nialloy), and meanwhile due to the robust mechanical adhesion and one-dimensional carrier transportation architecture firmly contacted to the metal, the metal substrate-supported Co3O4 arrays could act as a promising electrode material and be straightforwardly integrated into electronic and electrochemical nanodevices. © 2009 American Chemical Society.

摘要：
SnO<inf>2</inf> nanorod array grown directly on alloy substrate has been employed as the working electrode of H<inf>2</inf>O<inf>2</inf> biosensor. Single-crystalline SnO<inf>2</inf> nanorods provide not only low isoelectric point and enough void spaces for facile horseradish peroxidase (HRP) immobilization but also numerous conductive channels for electron transport to and from current collector;thus, leading to direct electrochemistry of HRP. The nanorod array-based biosensor demonstrates high H<inf>2</inf>O<inf>2</inf> sensing performance in terms of excellent sensitivity (379 μA mM<sup>-1</sup> cm<sup>-2</sup>), low detection limit (0.2 μM) and high selectivity with the apparent Michaelis-Menten constant estimated to be as small as 33.9 μM. Our work further demonstrates the advantages of ordered array architecture in electrochemical device application and sheds light on the construction of other high-performance enzymatic biosensors. ©The Author(s) 2010.

摘要：
Direct electrochemistry of horseradish peroxidase (HRP) was realized in a dextran (De), 1-ethyl-3-methylimidazolium ethylsulphate ([EMIM]EtOSO <inf>3</inf>) and V<inf>2</inf>O<inf>5</inf> nanobelt composite material modified carbon ionic liquid electrode (CILE). Spectroscopic results indicated that HRP retained its native structure in the composite. A pair of well-defined redox peaks of HRP appeared in pH 3.0 phosphate buffer solution with the formal potential of -0.213 V (vs. SCE), which was the characteristic of HRP heme Fe(III)/Fe(II) redox couple. The result was attributed to the specific characteristics of De-IL-V<inf>2</inf>O<inf>5</inf> nanocomposite and CILE, which promoted the direct electron transfer rate of HRP with electrode. The electrochemical parameters of HRP on the composite modified electrode were calculated and the electrocatalysis of HRP to the reduction of trichloroacetic acid (TCA) was examined. Under the optimal conditions the reduction peak current increased with TCA concentration in the range from 0.4 to 16.0 mmol L <sup>-1</sup>. The proposed electrode is valuable for the third-generation electrochemical biosensor. ©2010 Elsevier B.V. All rights reserved.

摘要：
Rheological phase (RP) method has been successfully applied to synthesize a promising cathode material LiNi<inf>0.65</inf>Co<inf>0.25</inf>Mn <inf>0.1</inf>O<inf>2</inf>. X-ray diffraction, X-ray photoelectron spectroscopy, inductively coupled plasma and transmission electron microscope are used to investigate the structure, composition and morphology, respectively. XRD result shows that the as-prepared powder has a layered α-NaFeO <inf>2</inf> structure. XPS pattern reveals that the Ni ions have valences of 2+ and 3+, and the Co and Mn are 3+, 4+, respectively. The electrode consisting of the obtained powder presents the better electrochemical properties, which is attributed to the fewer amounts of Ni<sup>2+</sup> ions and the smaller particles. All the results suggest that the rheological phase method is a promising technique for the preparation of LiNi<inf>0.65</inf>Co <inf>0.25</inf>Mn<inf>0.1</inf>O<inf>2</inf> cathode material of lithium-ion batteries.

摘要：
Three-dimensional (3D) dendrite-shaped CuO hollow micro/nanostructures have been prepared via a Kirkendall-effect-based approach for the first time and have been demonstrated as a high-performance anode material for lithium-ion batteries The as-prepared hollow structures were investigated by scanning electron microscopy, transmission electron microscopy, X-ray diffraction, and electrochemical properties. A CuO hollow structure composed of nanocubes outside and a dense film inside was selected as a typical example of the optimized design, it exhibited significantly improved cyclability at a current rate of 0 5 C, with the average Coulombic efficiency of similar to 97.0% and 57 9% retention of the discharge capacity of the second cycle after 50 cycles The correlation between the structure features of the hollow CuO and their electrochemical behavior was discussed in detail. Smaller size of primary structure and larger internal space of electrode materials are crucial to better electrochemical performance. This work represents that Kirkendall effect is a promising method to fabricate excellent hollow electrode materials for Li-ion batteries (C) 2010 Elsevier Inc. All rights reserved

摘要：
ZnO nanospindles were synthesized by PVP-assisted hydrothermal growth and ZnO@ZnS core-shell microspindles were successfully fabricated by sulfidation of ZnO nanospindles via a facile chemical synthesis. The as-obtained samples were characterized by X-ray diffraction, field emission scanning electron microscopy, transmission electron microscopy, energy dispersive X-ray spectroscopy and fluorescence spectrophotometer. The results showed that the pure ZnO nanospindles were hexagonal wurtzite crystal structure and the ZnS nanoparticles were sphalerite structure with the size of about 40 nm grown on the surface of the ZnO nanospindles. The measurement of luminescence revealed that ZnO@ZnS core-shell microspindles integrated the luminescent effect of ZnO and ZnS. The broad blue emission of ZnO@ZnS core-shell microspindles were dramatically enhanced, while the orange emission disappeared. In addition, a possible formation mechanism of ZnO@ZnS core-shell microspindles was also suggested based on the results of the experiments. © 2008 Elsevier B.V. All rights reserved.

摘要：
Multi-arm PbS nanostructures were successfully synthesized by chemical synthesis via the reaction between lead acetate trihydrate and element sulfur by a solvothermal route. X-ray diffraction, scanning electron microscopy, transmission electron microscopy, ultraviolet-visible spectroscopy and photoluminescence spectroscopy were used to characterize the PbS crystals. It was shown that well-dispersed and multi-arm PbS crystals were formed. It was also demonstrated that the morphologies of PbS crystals were significantly influenced by treatment temperature, reaction time and different sulfur sources. A growth process was proposed for the formation of multi-arm PbS crystals. The ultraviolet-visible absorption peak of PbS exhibited a large blue-shift and the luminescence spectra had a strong and broad emission band centered at 385 nm. ©2009 Elsevier B.V.

摘要：
This manuscript presents the preparation and characterization of ZnO/ZnS nanostructured materials through sulfuration conversion from ZnO nanorods by a simple chemical synthesis. ZnO nanorods are synthesized by SDS-assisted hydrothermal growth. X-ray diffraction (XRD), field emission scanning electron microscopy (FESEM), energy dispersive X-ray spectroscopy (EDS) and transmission electron microscopy (TEM) techniques are used to characterize the ZnO nanorods and the novel ZnO/ZnS nanocomposites. The results show that the ZnO nanorods are wurtzite crystal structure and the ZnS nanoparticles are sphalerite structure with the average size of about 10 nm grown on the surface of the ZnO nanorods. The measurements of the optical properties reveal that ZnO/ZnS nanocomposites have integrated the photoluminescent effect of ZnO and ZnS. Comparing to the bare ZnO nanorods with the ultraviolet, blue and green emissions of the ZnO/ZnS nanocomposites are dramatically enhanced, while the orange emission is passivated. In addition, the growth mechanism of ZnO/ZnS nanocomposites is discussed preliminarily. ©2008 Elsevier B.V. All rights reserved.

摘要：
In this paper, we prepared the ZnO nanoparticles by a simple hydrothermal method and fabricated the ZnO/SiO<inf>2</inf> core/shell nanostructures through a sol-gel chemistry process successfully. The hollow SiO<inf>2</inf> nanostructures were obtained by selective removal of the ZnO cores. The structure, morphology and composition of the products were determined by the techniques of X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FT-IR), field emission scanning electron microscopy (FESEM), energy dispersive X-ray spectroscopy (EDS) and transmission electron microscopy (TEM). The results indicated that the ZnO nanoparticles were sphere-like shape with the average size of 60 nm and belonged to hexagonal wurtzite crystal structure. With the coating of SiO<inf>2</inf>, the vibration modes of Si-O-Si and Si-OH were found. Furthermore, the measurement results of optical properties showed that spectra of bare ZnO nanoparticles and ZnO/SiO<inf>2</inf> core/shell nanocomposites exhibited similar emission features, including a blue emission peak and an orange emission band. ©2008 Elsevier Ltd.

摘要：
This paper describes a simple and versatile method for growing highly anisotropic rectangular shaped nanobat-like CuO nanostructures by simple, low temperature and cost effective hydrothermal method. Field emission scanning electron microscopy illustrated that these CuO nanostructures have diameter of ∼70 nm, thickness of ∼8 nm and length of ∼174 nm. Structural analysis reveals that the CuO nanostructures have a high crystal quality with monoclinic crystal structure. X-ray photoelectron spectroscopy studies demonstrate that the sample is composed of CuO. The Raman study also indicates the single phase property and high crystallinity of as-grown CuO nanostructures. The plausible growth mechanism for the formation of nanobat-like CuO structure is proposed. © 2009 Elsevier B.V. All rights reserved.

摘要：
CdS nanostructured materials were prepared by a chemical synthesis via the reaction of Cd(NO3)2·4H2O and various sulfur sources. The products were characterized by X-ray powder diffraction (XRD) and transmission electron microscopy (TEM). The results indicated that the samples prepared with Na2S·9H2O were zinc blende crystal structure in sphere-like shape and the products prepared with thiourea and sulfur were both wurtzite crystal structures in rod-like shape. The room-temperature luminescence revealed that all the CdS nanostructured materials had a broad green emission band and a red emission band. In addition, the growth mechanisms of the CdS nanocrystals were preliminarily discussed.

Bi2WO6 hierarchical structures constructed by a number of square nanoplates of average approximately 70 nm in side length and approximately 25 nm in thickness have been synthesized by a hydrothermal method at 180 degrees C. The single-crystal subunit nanoplates with (002) as their two-dimensional (2D) surfaces assembled orderly using both their edges and faces into free-standing films. It was found that the self-assembled growth of these hierarchical structures strongly depended on surfactant Cetyl Trimethyl Ammonium Bromide (CTAB), the amounts of the starting materials and the molar ratio of precursors (Bi3+ to WO4(2-)), etc. The growth mechanism was discussed based on the comparative experimental results.

摘要：
Carbon/ZnO nanorod arrays on nickel substrate have been fabricated over a large area by the simple carbonization of preadsorbed glucose on ZnO arrays at 500 °C in argon gas. The uniform coating of average 6 nm carbon shell on ZnO nanorod surface is confirmed. The novel array architecture possesses both the electroactivity of carbon and the electrochemical advantages of array structure on conductive substrate. When used as anode for Li ion batteries, it displays significantly improved performance in terms of cycling stability and rate capability. The observed lithium storage ability ranges among the best reported to date for ZnObased anode. We believe that the novel carbon-coating route is general and can be extendable to other metal oxide nanoarray electrodes. ©2009 American Chemical Society.

摘要：
SnO<inf>2</inf> nanorod arrays have been prepared on large-area flexible metallic substrates (Fe-Co-Ni alloy and Ni foil) via a hydrothermal process for the first time and have been demonstrated as a high-performance anode material for lithium ion batteries. Electrochemical behavior is found to depend crucially on the structural parameters of the array. An array consisting of SnO <inf>2</inf> nanorods of average 60 nm in diameter and 670 nm in length delivers a reversible capacity of as high as 580 mAh g<sup>-1</sup> after 100 cycles (at 0.1C) and shows excellent rate capability (350 mAh g<sup>-1</sup> at the 5C rate). Structural disintegration and agglomeration were not observed for SnO<inf>2</inf> arrays even after 50 cycles. ©The Royal Society of Chemistry 2009.

摘要：
The formation process of ZnO/ZnS core/shell microcomposites and ZnS microspindles prepared by the reaction of ZnO colloids and thioacetamide under hydrothermal conditions was investigated in detail by Xray powder diffraction, field emission scanning electron microscopy , transmission electron microscopy and selected-area electron diffraction techniques. The precursors of spindlelike ZnO colloids were prepared by a hydrothermal method with the help of a surfactant. A growth mechanism was proposed to account for the formation of ZnO/ZnS core/shell microcomposites and ZnS microspindles. Luminescence measurement revealed that ZnO/ZnS core/shell microcomposites integrated the luminescence effect of ZnO and ZnS. The blue and green emissions were dramatically enhanced, while the orange emission disappeared. The results provide a good approach to tune the visible emission of the ZnO nanostructures by ZnS coating. © 2009 WILEY-VCH Verlag GmbH & Co. KGaA.

摘要：
A simple sonochemical route for the synthesis of Ag nanoparticles on ZnO nanorods is reported. Ultrasonic irradiation of a mixture of ZnO nanorods, Ag(NH<inf>3</inf>)<inf>2</inf> <sup>+</sup>, and formaldehyde in an aqueous medium yields ZnO nanorod/Ag nanoparticle composites. The powder X-ray diffraction of the ZnO/Ag composites shows additional diffraction peaks corresponding to the face-center-cubic structured Ag crystalline, apart from the signals from the ZnO nanorods. Scanning electron microscopy and transmission electron microscopy images of the ZnO/Ag composites reveal that the ZnO nanorods are coated with Ag nanoparticles with a mean size of several tens nanometer. The absorption band of ZnO/Ag composites is distinctly broadened and red-shifted, indicating the strong interfacial interaction between ZnO nanorods and Ag nanoparticles. This sonochemicalmethod is simple, mild and readily scaled up, affording a simple way for synthesis of other composites. ©2009 WILEY-VCH Verlag GmbH &Co. KGaA, Weinheim.
