Abstract

An ultrathin MoS2 was grown on CdS nanorod by a solid state method using sulfur powder as sulfur source for photocatalytic H2 production. The characterization result reveals that the ultrathin MoS2 nanosheets loaded on CdS has a good contact state. The photoelectrochemical result shows that MoS2 not only are beneficial for charge separation, but also works as active sites, thus enhancing photocatalytic activity. Compared with pure CdS, the photocatalytic activity of MoS2 loaded CdS was significantly improved. The hydrogen evolution rate on m(MoS2): m(CdS) = 1: 50 (m is mass) reaches 542 μmol/h, which is 6 times of that on pure CdS (92 μmol/h). This work provides a new design for photocatalysts with high photocatalytic activities and provides a deeper understanding of the effect of MoS2 on enhancing photocatalytic activity.
