摘要：
Five new Zn-II/Cd-II coordination polymers (CPs) based on a flexible bis(imidazole) ligand 9,10-bis((2-methyl-1H-imidazol-1-yl)methyl)anthracene (bmima) with three different aromatic carboxylic acid ligands have been synthesized under solvothermal conditions: {[Cd(bmima)(0.5)(atp)(H2O)]center dot DMF center dot 0.5H(2)O} (CP 1), {[Zn(bmima)(atp)]center dot DMF} (CP 2), {[Cd(bmima)(bpdc)]center dot 2DMF} (CP 3), and {[M(bmima)(0.5)(oda)]center dot DMF center dot H2O} (M = Zn for CP 4 and Cd for CP 5), (H(2)atp = 2-aminoterephthalic acid; H(2)bpdc = [1,1 & PRIME;-biphenyl]-4,4 '-dicarboxylic acid and H(2)oda = 4,4 '-oxydibenzoic acid). CP 1 displays a 3,4-connected TiSc topology 3D framework with vertex symbols of {4(2)center dot 6 center dot 10(2)center dot 12}{4(2)center dot 6}. CP 2 and CP 3 both feature 2D layer structures with a five-fold interpenetration framework for CP 3. CP 4 and CP 5 both show a 3D "pillar-layer " structure with pcu alpha-Po topology. The structural differences of the five CPs may be due to the diverse coordination modes of dicarboxylate ligands and the conformation of flexible N-donor ligands. Moreover, CP 1 and CP 3 are two good fluorescent sensors for the detection of Fe3+, Cr2O72- and TNP. The mechanism of the two sensors shows that the fluorescent sensing process toward Fe3+ and Cr2O72- is mainly attributed to the competitive absorption process, while both competitive absorption and the more efficient FRET mechanism for TNP, respectively, which indicates that CP 1 and CP 3 can serve as two fluorescence sensors to sensitively and selectively detect the presence of Fe3+ and Cr2O72- in water.

摘要：
Copper-based nanomaterials are compelling for high-efficient, low-cost electrocatalytic CO(2) reduction reaction (CO(2)RR) due to their exotic electronic and structural properties. However, controllable preparation of copper-based two-dimensional (2D) materials with abundant catalytically active sites, that guarantee high CO(2)RR performance, remains challenging, especially on a large scale. Here, an in situ vertical growth of scalable metallic 2D Cu(2)Te nanosheet arrays on commercial copper foils is demonstrated for efficient CO(2)-to-CH(4) electrocatalysis. The edge-oriented growth of Cu(2)Te nanosheets with tunable sizes and thicknesses is facilely attained by a two-step process of chemical etching and chemical vapor deposition. These active sites abounding on highly exposed edges of Cu(2)Te nanosheets greatly promote the electroreduction of CO(2) into CH(4) at a potential as low as -0.4 V (versus the reversible hydrogen electrode), while suppressing hydrogen evolution reaction. When a flow cell is employed to accelerate the mass transfer, the faradaic efficiency reaches ∼63% at an applied current density of 300 mA cm(-2). These findings will provide great possibilities for developing scalable, energy-efficient Cu-based CO(2)RR electrocatalysts.

摘要：
The in-depth mechanism on the simultaneous activation of O2 and surface lattice O2− on one active metallic site has not been elucidated yet. Herein, we report a strategy for the construction of abundant oxygen activation sites by rational design of Cu1/TiO2 single atom catalysts (SACs). The charge transfer between isolated Cu and TiO2 support generates abundant CuI and 2-coordinated Olat sites in Cu1−O−Ti hybridization structure, which facilitates the chemisorption and activation of O2 molecules. Simultaneously, the Cu1−O−Ti induced TiO2 lattice distortion activate the adjacent surface lattice O2−, achieving the dual activation of O2 and surface lattice O2−. The Cu1−O−Ti active site switches the CO oxidation mechanism from Eley-Rideal (80 °C) to Mars–van Krevelen route (200 °C) with the increase of reaction temperature. The dual activation of O2 and surface lattice O2− can by modulating the electron properties of SACs can boost the heterogeneous catalytic oxidation activity.
