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 H2 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...
