Porous α-Fe2O3microrods with net-worked nanostructure were synthesized by a simple low-temperature hydrothermal method that using the FeC2O4·2H2O as sacrifice template. X-ray diffraction, scanning electron microscopy, transmission electron microscopy and Brunauer Emmett Teller N2adsorption-desorption analysis were used to characterize the morphology and structure of as-prepared products. Furthermore, the gas sensing properties of the porous α-Fe2O3microrods were evaluated and compared with compact α-Fe2O3nanoparticles. All results reveal that the as-prepared porous &al...
