As a potential candidate photocatalyst, high carrier recombination rate of ZnIn2S4 limits its application, and it is necessary to improve its performance by constructing suitable structure. In this study, Bi2WO6/ZnIn2S4 composites with Z-scheme structure were successfully prepared, and they show enhanced photocatalytic performance. The BWO/ZIS-2 shows the highest photocatalytic efficiency of 97.5% within 60 min for degrading methyl orange (MO), and maintain an efficiency of more than 90% after five reuses. Moreover, BWO/ZIS-2 can degrade various organic pollutants without selectivity. Rapid transfer of carriers inhibits the recombination of e− and h+, which is responsible for high photocatalytic activity of Bi2WO6/ZnIn2S4.

具有Z方案结构的Bi 2 WO 6 / ZnIn 2 S 4的构建,具有有效的光催化性能
作为潜在的候选光催化剂,ZnIn 2 S 4的高载流子复合率限制了其应用,并且有必要通过构建合适的结构来提高其性能。本研究成功地制备了具有Z型结构的Bi 2 WO 6 / ZnIn 2 S 4复合材料,并显示出增强的光催化性能。BWO / ZIS-2在60分钟内对降解甲基橙(MO)表现出最高的光催化效率,为97.5%,并且在五次重复使用后仍保持90%以上的效率。而且,BWO / ZIS-2可以无选择地降解各种有机污染物。载波抑制e的重组的快速转移-和h+负责Bi 2 WO 6 / ZnIn 2 S 4的高光催化活性。
