Abstract
The Ag modified Fe-doping TiO2 nanoparticles and nanowires (Ag@Fe–TiO2 NPs and NWs) were prepared by convenient modified sol–gel and one-pot solvothermal method, respectively. The high photocatalytic activities of the Ag@Fe–TiO2 photocatalysts for H2 production and formaldehyde degradation were ascribed to the extended light-responsive range, accelerated migration, increased specific surface area and suppressed recombination of photogenerated carriers. All Ag@Fe–TiO2 samples showed good photochemical stabilities for reusage. The mechanisms for the significantly enhanced photocatalytic activities of the Ag@Fe–TiO2 NPs and NWs were proposed. Our research provides valuable contributions in the future preparations and applications for TiO2 based photocatalysts.
