Research Progress on Special-morphology Photocatalysts

Abstract Photocatalytic technology can convert solar energy into chemical energy efficiently, so it is an important method to solve the energy crisis and environmental pollution. Some special-morphology photocatalysts have the advantages of large specific surface area, low photogenerated electron-hole pair recombination rate or high light energy utilization rate. This article summarizes the synthesis strategies and photocatalytic performance of photocatalysts with different morphologies (nanowires, nanorods, nanotubes, nanosheets, core-shell structures). Various photocatalysts with special morphologies can be prepared by the hydrothermal method and the prepared photocatalysts show excellent catalytic performance. The reasons for the improvement of their photocatalytic performance include the following two aspects:1) more reactive sites can be provided; 2) the separation efficiency of photogenerated electron-hole pairs is improved. Finally, the research direction of developing photocatalysts with special morphologies is also put forward.
