A simple route for the preparation of a reduced graphene oxide–zinc sulfide (RGO–ZnS) nanocomposite via one-pot hydrothermal synthesis has been reported. The chemical composition, morphology, and structure of the RGO–ZnS photocatalyst were fully characterized via standard analysis methods, and then, its photocatalytic applications were surveyed through the synthesis of benzazoles. It was found that the photocatalytic properties of pure ZnS were enhanced with the incorporation of RGO. Herein, we present the RGO–ZnS composite as a new photocatalyst for the synthesis of benzazoles through oxidative cyclization of benzylamines with 1,2-ortho-phenylene disubstituted compounds as a precursor under room temperature, visible light irradiation, and acid/oxidant-free conditions.

还原氧化石墨烯-硫化锌（RGO-ZnS）纳米复合材料：一种在可见光照射下将苄胺氧化环化为苯并唑类的新型光催化剂

已经报道了一种通过一锅水热合成制备还原氧化石墨烯-硫化锌（RGO-ZnS）纳米复合材料的简单途径。通过标准分析方法对 RGO-ZnS 光催化剂的化学成分、形貌和结构进行了充分表征，然后通过苯并唑类的合成对其光催化应用进行了调查。发现纯ZnS的光催化性能随着RGO的掺入而增强。在此，我们提出了 RGO-ZnS 复合材料作为一种新的光催化剂，用于通过苄胺与 1,2-邻位的氧化环化合成苯唑类。- 亚苯基二取代化合物在室温、可见光照射和无酸/无氧化剂条件下作为前体。
