摘要：

TiO2 grown on MoSe2 nanosheets was synthesized by a simple process and explored as photocatalyst for hydrogen generation. In visible light, hydrogen generation rate over the MoSe2/TiO2 photocatalyst was found to be 468.2 mu mol h(-1) g(-1), much higher than the corresponding rates obtained over the MoSe2, TiO2 and their physical mixture. It is suggested that the good absorption of MoSe2 to visible light and the improved charge separation by the interface of MoSe2/TiO2 greatly promote hydrogen generation rate, as supported by the transient photocurrent responses and electrochemical impedance spectra recorded.
