The incorporated Zn_0.5Cd_0.5S (ZCS) nanorods with MoS₂/RGO cocatalysts by a simultaneous reduction reaction was reported. The preparation of RGO and formation of MoS₂ with intimate interfacial contact with ZCS were achieved. Through the optimizing of each component proportion, the ZCS@MoS₂/RGO hybrid with 1.5 wt % MoS₂ and 3 wt % RGO showed the highest photocatalytic H₂ production activity (2.31 mmol/h) with long time stability (50 h). The relative mechanism has been investigated. It is believed that the stabilizing and improving solar H₂ generation is originating from dual charge transfer pathway from excited ZCS to RGO, then to MoS₂ due to intimate interfacial structure.
