Construction of heterostructure by intimately interfacing two or more semiconductor materials with different geometrical and electronically energetic alignments at nanoscale is very important to achieve the composite photocatalysts with a high photocatalytic efficiency. Here, we in-situ prepared an intimate contact MoS2/ZnIn2S4 heterostructure photocatalyst by a one-pot solvothermal reaction. The MoS2/ZnIn2S4 heterostructure significantly enhanced the photocatalytic H-2 evolution of ZnIn2S4 under visible light illumination. The hydrogen evolution rate reaches 3891.6 mu mol g(-1) h(-1) over 5%-MoS2/ZnIn2S4, which exceeded the photocatalytic activity of Pt-loaded ZnIn2S4 samples. The subtle atomic-level intimate contact and strong interactions between ZnIn2S4 and MoS2 was ascribed to a highly efficient charge carrier separation and thus photocatalytic activity for MoS2/ZnIn2S4. These results provide inspiration for the design of composited photocatalysts with efficient photo catalytic H-2 evolution.
