Metal oxides with proper pore structure and tiny particle size can be utilized to gas sensor by promoting the diffusion and adsorbed quantity of target gas molecules. Herein, porous ZnFe2O4nanorods with net-worked nanostructure were synthesized by a simple low-temperature hydrothermal strategy using the ZnFe2(C2O4)3precursor as self-template. The images of electron microscopy obviously depicted the ZnFe2O4size of primary particle is around 20 nm and abundant through pore structure. In addition, the N2adsorption-desorption results indicate the specific surface area and the pore size are ab...
