The MoS2/ZnIn2S4 composites with MoS2 anchored on the surface of ZnIn2S4 microspheres were fabricated by a facile solvothermal method. To clarify the crystal phases, morphologies, chemical compositions, optical properties, and special surface areas of the obtained photocatalysts, the corresponding characterization measurements were performed. The photocatalytic H-2 evolution activities of MoS2/ZnIn2S4 composites were evaluated and compared with using lactic acid as sacrificial reagents. The results showed that integrating MoS2 with ZnIn2S4 could remarkably boost the photocatalytic H-2 evolutio...
