本文通过简单的水热法将Au/g - C3N4等离子体光催化剂复合材料与3D ZnIn2S4纳米片整合，成功构建了一种具有3D分级微结构的新型Au/g - C3N4/ZnIn2S4等离子体光催化剂异质结复合材料。首先将Au纳米粒子锚定在原始g - C3N4材料表面，得到Au/g - C3N4等离子体光催化剂。由于Au纳米粒子的表面等离子体共振，所获得的Au/g - C3N4等离子体光催化剂与原始g - C3N4相比，在可见光响应下对水分解制氢表现出显著提高的光催化活性。进一步将Au/g - C3N4等离子体光催化剂与3D ZnIn2S4纳米片结合构建异质结复合材料。由于Au/g - C3N4中Au纳米粒子的表面等离子体共振以及Au/g - C3N4和ZnIn2S4界面处的异质结结构的协同效应，所制备的Au/g - C3N4/ZnIn2S4等离子体光催化剂异质结复合材料在可见光响应下对水分解制氢表现出优异的光催化活性，分别比原始C3N4和ZnIn2S4纳米片高约7.0倍和6.3倍。本研究工作可能为探索其他具有优异性能的高效异质结光催化剂提供一些见解。（C）2021氢能出版有限责任公司。由爱思唯尔有限公司出版。保留所有权利。
In this paper, a novel Au/g-C3N4/ZnIn2S4 plasma photocatalyst heterojunction composite with 3D hierarchical microarchitecture has been successfully constructed by integrating Au/g-C3N4 plasmonic photocatalyst composite with 3D ZnIn2S4 nanosheet through a simple hydrothermal process. The Au nanoparticles were firstly anchored on the surface of pristine g-C3N4 material to get Au/g-C3N4 plasmonic photocatalyst. Ascribing to the surface plasmon resonance of Au nanoparticles, the obtained Au/g-C3N4 plasmonic photocatalyst shows a significant improved photocatalytic activity toward hydrogen production from water with visible light response comparing with pristine g-C3N4. Further combining Au/gC(3)N(4) plasmonic photocatalyst with 3D ZnIn2S4 nanosheet to construct a heterojunction composite. Owing to the synergistic effect of the surface plasmon resonance of Au nano particles in Au/g-C3N4 and the heterojunction structure in the interface of Au/g-C3N4 and ZnIn2S4, the prepared Au/g-C3N4/ZnIn2S4 plasma photocatalyst heterojunction composite shows an excellent photocatalytic activity toward hydrogen production from water with visible light response, which is around 7.0 and 6.3 times higher than that of the pristine C3N4 and Znln(2)S(4) nanosheet, respectively. The present work might provide some insights for exploring other efficient heterojunction photocatalysts with excellent properties. (C) 2021 Hydrogen Energy Publications LLC.
