The intrinsic ZnSn(OH)_(6)has a wide band gap(about 4.0eV), and the valence band and conduction band position make it have high redox potential, which is conducive to driving the photocatalytic redox reaction. It shows a good application prospect in the fields of environmental purification and energy development. In this review, the crystal structure and surface structure of ZnSn(OH)_(6)are introduced according to its physical and chemical properties. Based on the application of Zn Sn(OH)_(6)in photocatalysis, the modification strategies of ZnSn(OH)_(6)are outlined, including defect engineering, element doping, heterojunction establishment and crystal control. Finally, the application of ZnSn(OH)_(6)in energy development(hydrogen production and carbon dioxide reduction) and environmental treatment(sewage disposal and air purification) are emphasized. At the same time, it is pointed out that the practical application of ZnSn(OH)_(6)-based photocatalyst is still in the preliminary stage. In the future,it is necessary to further explore the accuracy of the modification strategy for ZnSn(OH)_(6)application requirements, expand its application fields, provide approaches and ideas for follow-up research, and accelerate the process of its industrial application.
