Abstract
In this paper, we report a new g-C3N4/MoS2/TiO2 composite material as a high-performance photocatalyst for H2 evolution. Without a noble-metal cocatalyst, the g-C3N4/MoS2/TiO2 composite reaches a high H2 production rate of 125μmolh−1 when the content of the g-C3N4/MoS2 cocatalyst is 1.0wt.% and the content of g-C3N4 in this cocatalyst is 10wt.%. This unusual photocatalytic activity is attributed to the positive synergetic effect between the MoS2 and g-C3N4 components in this cocatalyst, which serve as an electron collector and a source of active adsorption sites, respectively.
