摘要：
Herein, a series of novel SrTiO3 (STO) based photocatalysts loaded with Cu-Pt bimetallic co-catalysts have been synthesized through a simple photodeposition process. This photocatalyst of STO/Cu-Pt displayed enhanced photocatalytic activity for hydrogen generation from water in the presence of methanol as a sacrificial reagent. Moreover, the hydrogen generation efficiency over the STO/Cu95-Pt5 photocatalyst was about 2.79 and 1.76 times of STO/Cu100-Pt0 and STO/Cu0-Pt100, respectively. Thus, this Cu-Pt synergetic cocatalyst presents an inexpensive and high efficiency cocatalyst to achieve efficient hydrogen evolution from water.
