摘要：

Photocatalytic CO2 reduction into solar fuels over photocatalysts has theoretically and practically become a hot research topic. Herein, we fabricated a novel hybrid TiO2 nanofiber coated by CuInS2 nanoplates through a hydrothermal method. The materials were characterized by X-ray diffraction, electron microscopes, UV-vis absorption spectra, nitrogen sorption, X-ray photoelectron spectroscopy and electrochemical impudence spectroscopy. The resulting TiO2/CuInS2 hybrid nanofibers exhibit superior photocatalytic activity for CO2 reduction under irradiation, due to the generation of direct Z-scheme heterojunction between TiO2 and CuInS2. This work may provide an alternate methodology to design and fabricate multicomponent TiO2-based photocatalyst for high-efficiency CO2 photoreduction.
