摘要：

WS2 nanosheets CdS nanorods with heterojunctions were prepared by an ultrasonic/exfoliation method using dimethylformamide as the dispersing agent. CdS nanorods were coupled with small WS, nanosheets as a result of exfoliation. An excellent hydrogen production rate of 1222 mu mol h(-1) mg of catalyst) was achieved over the WS2-CdS composite with a WS2-to-CdS mass ratio of 1.6:1 under visible-light irradiation (lambda > 400 nm). The efficient evolution of hydrogen is attributed to promotion of the separation of photo generated charge carriers due to the presence of heterojunctions created on the surface.
