Enhancement of the Photocatalytic Activity Under Visible-Light Irradiation over N-doped TiO2 Modified by Platinum Chloride

摘要

N-doped TiO2 adsorbed platinum chloride (PtCl_x/N-TiO2, x being an unidentified number) was found to show much higher photocatalytic activity than either N-TiO2 or PtCl_x/TiO2 for the decomposition of acetic acid into CO2 and H2O under Visible-light irradiation, while neither PtCl_x/SiO2, PtCl_x/Al2O3 nor an aqueous solution of H2PtCl6 was active. An enhancement of the photo-activity on PtCl_x/N-TiO2 has been proposed as a Z-scheme mechanism.
