Improved photoactivities for CO2 conversion and phenol degradation of α-Fe2O3 nanoparticles by co-coupling nano-sized BiPO4 and CuO to modulate electrons

摘要: Abstract It's highly desired to design and fabricate effective α-Fe2O3-based photocatalysts by increasing the surface area, promoting charge separation providing catalytic function. Herein, specific area-enlarged α-Fe2O3 (SE-FO) nanoparticles have been successfully synthesized a functional molecule-modulated phase-separated hydrothermal method, with high photocatalytic activities for CO2 conversion phenol degradation. The of SE-FO could be greatly improved coupling nano-sized BiPO4 via an in-situ introduction method. This is attributed coupled as high-energy platform accept photogenerated electrons from so enhance mainly means photovoltage spectra fluorescence spectra-related amount produced •OH species. Moreover, are further introducing proper nanocrystalline CuO simple impregnation process. It confirmed based on temperature-programmed desorption electrochemical reduction measurements that photoactivity introduced co-catalyst electron-induced reactions. Remarkably, optimized nanocomposite exhibits about 3-time improvement compared pristine α-Fe2O3. work would provide feasible route high-activity
