Nitrogen-doped graphene-ZnS composite (NG-ZnS) was synthesized by thermal treatment of graphene-ZnS composite (G-ZnS) in NH₃ medium. In the second step, the as-synthesized samples were deposited on indium tin oxide glass (ITO) by electrophoretic deposition for photocatalytic hydrogen evolution reaction. The as-prepared NG-ZnS-modified ITO electrode displayed excellent photocatalytic activity, rapid transient photocurrent response, superior stability and high recyclability compared to the pure ZnS and G-ZnS-modified ITO electrode due to the synergy between the photocatalytic activity of ZnS nanorods and the large surface area and high conductivity of N-graphene.

通过在NH ₃介质中热处理石墨烯-ZnS复合材料（G-ZnS），合成了氮掺杂的石墨烯-ZnS复合材料（NG-ZnS）。在第二步中，通过电泳沉积将合成后的样品沉积在氧化铟锡玻璃（ITO）上，以进行光催化氢释放反应。与纯ZnS和G-ZnS修饰的ITO电极相比，由于ZnS纳米棒的光催化活性之间的协同作用，所制备的NG-ZnS修饰的ITO电极显示出优异的光催化活性，快速的瞬态光电流响应，优异的稳定性和高可回收性。 N-石墨烯的大表面积和高电导率。
