中文摘要：
本项目采用水热、溶剂法等低温合成技术，在可控条件下制备具有特定形貌、组成、结构的高活性纳米ZnS固溶体可见光催化材料，并研究不同制备工艺及条件对催化剂的微观形貌、电子结构及催化性能的影响。采用透射和扫描电镜等手段研究不同工艺参数下材料的形貌及微观结构，探讨其形成机制；采用密度泛函和Rietveld法研究催化剂的电子结构（态密度、能带结构等）和晶体结构（键长、键角、超结构、结构畸变等）；采用光催化性能评价装置测试不同条件下样品的可见光分解水制氢性能。讨论固溶体形貌、组成、结构与光催化制氢性能的关系，研究光催化机理，寻找提高太阳能利用率和量子产率的有效途径，为设计开发新型高效的光催化材料提供理论和实验依据。
