摘　　要：随着社会经济的高速发展,能源的短缺和生态的破坏引起了人们的关注。近年来,寻找合适的解决方案已成为关注的重点。作为一种绿色环保技术,光催化由于其高效、低成本等优点而成为能源和环境问题的研究热点。在许多光催化材料中,三元硫化物硫化铟锌(ZnIn_(2)S_(4))由于具有可见光响应特性、简单的制备方法和出色的稳定性而表现出巨大的潜力。然而,较高的载流子复合率限制了其光催化性能。近年来,许多研究报道了改性ZnIn_(2)S_(4)以提高其光催化性能,在此,本文详细介绍了各种改性研究,包括ZnIn_(2)S_(4)单体的合成、半导体化合物的结构、贵金属沉积、碳元素改性、离子掺杂。然后,系统完整地总结了ZnIn_(2)S_(4)在光催化、降解有机污染物、去除六价铬、还原CO;和有机合成等方面表现出的光催化特性和机理。最后,对ZnIn_(2)S_(4)的发展前景提出了展望,以期ZnIn_(2)S_(4)光催化剂得到更广泛和深入的研究,尽快在实际生产中得到应用。With rapid development of social economy,shortage of energy and destruction of ecology have gradually aroused people’s strong concern.In recent years,finding the suitable solution has become the focus of attention.As a green environmental protection technology,photocatalysis has become a research hotspot to deal with energy and environmental issues because of its high efficiency and low cost.In many photocatalytic materials,ternary sulfide Indium Zinc Sulfide(ZnIn_(2)S_(4))has shown great potential due to visible-light-responding characteristics,simple preparation and excellent stability.However,high carrier recombination rate of the ZnIn_(2)S_(4)limits its photocatalytic activity.In recent years,many studies on modifying ZnIn_(2)S_(4) have been reported.Here,different modification researches are introduced in detail including synthesis of ZnIn_(2)S_(4) monomer,construction of semiconductor compounds,noble metal deposition,carbon element modification,and ion doping.Then,their photocatalytic properties and corresponding mechanisms including hydrogen evolution,degradation of organic pollutants,reduction of hexavalent chromium and CO;,and organic synthesis are systematically summarized.Finally,development direction and prospect of ZnIn_(2)S_(4) are put forward for more extensive and in-depth research on photocatalytic properties and application in practical production as soon as possible.
