摘要/Abstract

摘要： 采用简单的共沉淀法制备了新型ZnSn(OH)₆/SrSn(OH)₆复合光催化剂。利用X射线衍射(XRD)、X射线光电子能谱(XPS)、紫外可见-漫反射吸收光谱(UV-Vis)、N₂吸附脱附、扫描电镜(SEM)、透射电镜(TEM)对样品的结构、形貌和光吸收性质进行了表征,并以甲苯为目标污染物对其光催化性能进行评价。结果表明,与纯相SrSn(OH)₆和ZnSn(OH)₆相比,复合材料ZnSn(OH)₆/SrSn(OH)₆的紫外光吸收能力显著增强,光生载流子的复合效率降低,进而增强了其光催化降解甲苯的效率。复合样品ZSH/SSH-10摩尔比为10%对甲苯的降解率达到58%,是SrSn(OH)₆单体的1.35倍。循环使用5次后,ZSH/SSH-10的降解率仍保持51%以上,说明该催化剂具有良好的循环稳定性。

Abstract: A new type of ZnSn(OH)₆/SrSn(OH)₆ composite photocatalyst was prepared by a simple co-precipitation method. The structure, morphology and light absorption properties of the samples were characterized by XRD, XPS, UV-Vis, N₂ adsorption and desorption, scanning electron microscope(SEM), transmission electron microscope(TEM). Its photocatalytic performance was evaluated by toluene target pollutant. The results show that compared with the pure phase SrSn(OH)₆ and ZnSn(OH)₆, the composite material ZnSn(OH)₆/SrSn(OH)₆ has significantly enhanced ultraviolet light absorption capacity, and the recombination efficiency of photogenerated carriers reduce. Furthermore, the efficiency of photocatalytic degradation of toluene is enhanced. The degradation rate of toluene in the composite sample ZSH/SSH-10(molar ratio is 10%) is more than 58%, which is 1.35 times that of SrSn(OH)₆ monomer. The degradation of toluene for ZSH/SSH-10 catalyst is still 51% after recycling 5 times, indicating that the catalyst has good recycling stability.
