%X 水热法一步合成ZnS/还原氧化石墨烯（ZnS/RGO）复合材料，通过XRD、FTIR、Raman、SEM分析溶剂（乙醇、水）对ZnS/RGO复合材料形貌和结构的影响。结果表明，以乙醇为溶剂制备的ZnS颗粒尺寸小、均匀分散在石墨烯片层上，在形成ZnS纳米颗粒的同时将氧化石墨烯（GO）还原成石墨烯。对亚甲基蓝（MB）的光催化结果显示，ZnS/RGO复合材料具有优异的光催化性能，其光催化速率是纯ZnS颗粒的3.7倍，石墨烯作为优良光生电子的传输通道和收集体能够降低光生电子-空穴对的重新结合率，极大提高了ZnS/RGO复合材料的光催化性能。 The ZnS/reduced graphene oxide (ZnS/RGO) composites were synthesized via a one-pot hydrothermal synthesis. The effects of solvent (ethanol, water) on the morphology and structure of ZnS/RGO composites were analyzed by XRD, FTIR, Raman and SEM. The results show that small ZnS particles uniformly disperse on the graphene sheet when using ethanol as the solvent during the formation of ZnS nanoparticles and the reduction of graphene oxide (GO) occur simultaneously. The photocatalytic activity of the prepared ZnS/RGO composite was examined by the degradation of Methylene blue (MB). The experimental results suggest that the designed ZnS/RGO composite possess superior photocatalytic activity, which is 3.7 fold higher reaction rates for MB degradation than that of the pure ZnS nanoparticles. Graphene, as a good electron collector and transporter to reduce the photoinduced electron-hole pair recombination, can greatly improve the photocatalytic activity of ZnS/RGO composites. 四川理工学院人才引进项目（2017RCL38；2017RCL65）；国家自然科学青年基金（51301115；51701133
