摘　　要：硫化镉锌(ZnCdS)作为双金属硫化物固溶体被广泛应用于光催化领域,但其在实际应用中存在光吸收范围有限及光生电子-空穴对分离效率不高等问题。文章阐述了ZnCdS固溶体的结构特性,多样化制备方法与创新改性策略。在标志性实验工作中,重点阐述了通过微观形貌调控、构筑异质结及缺陷工程等手段对ZnCdS固溶体进行改性的研究进展。优化后的ZnCdS材料的光吸收范围得到有效拓宽,促进了光生电子-空穴对的分离,光催化效率显著增强。系统分析了影响ZnCdS光催化性能的关键因素,并详尽阐述了其在环境治理与能源转化等关键领域的实际应用与显著成效,为未来该材料的研究与应用提供参考。Zinc cadmium sulfide(ZnCdS)is widely used as a bimetallic sulfide solid solution in photocatalysis,however,it still has the problems of limited light absorption range and inefficient separation of photogenerated electron-hole pairs in practical applications.In this paper,the structural properties of ZnCdS solid solution,diversified preparation methods and innovative modification strategies are introduced in detail.A series of studies have demonstrated that the modification of ZnCdS solid solution by means of microscopic morphology modification,constructing heterojunction and defect engineering can effectively broaden the light absorption range of ZnCdS materials and promote the separation of photogenerated electron-hole pairs,thus significantly enhancing the photocatalytic efficiency.Meanwhile,the key factors affecting the photocatalytic performance of ZnCdS are systematically analysed,and its practical applications and remarkable results in key fields such as environmental treatment and energy conversion are elaborated.It provides an important reference and guidance for the future research and application of this material.
