摘要

本研究采用简单的液相杂交方法合成了具有纳米片微球结构的层叠Co3O4/ZnIn2S4 0D/3D p-n异质结纳米复合光催化剂。首先，采用水热法和高温法制备了三维层次化ZnIn2S4纳米片微球和0D Co3O4纳米颗粒。随后，将0D球形Co3O4纳米颗粒嵌入到ZnIn2S4纳米片微球中，构建p-n异质结纳米复合光催化剂。由于p-n异质结、内置电场和0D/3D层叠纳米片微球结构的协同作用，Co3O4/ZnIn2S4纳米复合材料在可见光驱动下的水制氢活性显著增强。优化后的ZnIn2S4纳米片微球的光催化性能约为原始ZnIn2S4纳米片微球的4.6倍，表观量子产率约为8.15%。并对可能的光催化机理进行了讨论。这些发现为设计和开发用于能源和环境应用的高效0D/3D p-n异质结光催化剂提供了有价值的见解。

A novel hierarchical Co3O4/ZnIn2S4 0D/3D p-n heterojunction nanocomposite for efficient visible-light-driven hydrogen production

In this study, a hierarchical Co₃O₄/ZnIn₂S₄ 0D/3D p-n heterojunction nanocomposite photocatalyst with a nanosheet microsphere structure was synthesized via a simple liquid-phase hybridization method. First, 3D hierarchical ZnIn₂S₄ nanosheet microspheres and 0D Co₃O₄ nanoparticles were synthesized using a hydrothermal method and a high-temperature process, respectively. Subsequently, the 0D spherical Co₃O₄ nanoparticles were embedded into the ZnIn₂S₄ nanosheet microspheres to construct a p-n heterojunction nanocomposite photocatalyst. Due to the synergistic effects of the p-n heterojunction, built-in electric field, and the 0D/3D hierarchical nanosheet microsphere structure, the Co₃O₄/ZnIn₂S₄ nanocomposite exhibited significantly enhanced photocatalytic activity for visible-light-driven hydrogen production from water. The optimized photocatalytic performance was approximately 4.6 times higher than that of the pristine ZnIn₂S₄ nanosheet microspheres, with an apparent quantum yield of around 8.15 %. The possible photocatalytic mechanism was also discussed. These findings provide valuable insights for the design and development of efficient 0D/3D p-n heterojunction photocatalysts for energy and environmental applications.
