摘　　要：羟基锡酸锌(ZnSn(OH)_(6))是一种具有多变价态和特殊电子结构的过渡金属锡酸盐。其禁带宽度较大,价带和导带位置使其具有较高的氧化还原电势,因而呈现出良好的光催化活性和较强的稳定性。在这篇综述中,首先概括了ZnSn(OH)_(6)光催化剂的晶体结构。其次,介绍了ZnSn(OH)_(6)基光催化剂的合成方法和改性策略。最后对ZnSn(OH)_(6)基光催化剂的未来发展进行了展望。Zinc hydroxyl stannate(ZnSn(OH)_(6)) is a representative hydroxyl compound with perovskite structure,and also a transition metal stannate with multiple valence states(Sn^(2+)/Sn^(4+)).Besides,the wide band gap of ZHS,and the positions of the valence and conduction bands make it have a high redox potential,thus showing good photocatalytic activity and strong stability.In this paper,the crystal structure,preparation method and the main influencing factors of photocatalytic performance over ZnSn(OH)_(6) materials were introduced.Meantime,the modification strategies and application of ZnSn(OH)_(6)-based photocatalysts in energy and environmental field were well exemplified.
