摘要：
CdMoO4/CdS@MoS2 ternary composite with MoS2 anchoring on the surface of CdMoO4/CdS were synthesized by a one-step hydrothermal approach and characterized by the corresponding techniques. The photocatalytic H-2 evolution activities were measured and compared with lactic acid as a sacrificial reagent. The results showed that the CdMoO4/CdS@MoS2 ternary composite exhibited more efficient photocatalytic H-2 evolution activity than those of CdMoO4/CdS, MoS2/CdMoO4, and MoS2/CdS binary composites. The significantly improved photocatalytic H-2 evolution activity could be attributed to more effective separation of photogenerated charge carriers over the CdMoO4/CdS@MoS2 ternary composite.
