含有氧空位的Bi2MoO6/ZnIn2S4 S型异质结用于光催化降解有机污染物
为提高Bi2MoO6基复合材料的光催化降解效率，采用溶剂热法制备了不同复合比例的Bi2MoO6/ZnIn2S4（x-BMO/ZIS）复合材料。通过RhB降解实验研究了催化剂用量、污染物浓度、无机盐离子和溶液pH对RhB降解效率的影响规律，揭示了BMO/ZIS异质结光催化降解机理。BMO/ZIS对RhB的去除率达到96.52%，分别是Bi2MoO6和ZnIn2S4的7.02倍和3.67倍，实现了少量光催化剂对高浓度RhB的有效降解。
To improve the degradation efficiency of Bi2MoO6-based composite materials, x-BMO/ZIS composites with different composite ratios were prepared by solvothermal method. The effects of catalyst dosage, RhB concentration, inorganic salt ions, and solution pH on the degradation efficiency and photocatalytic degradation of RhB were studied through degradation experiments. The photocatalytic degradation mechanism of x-BMO/ZIS heterojunction was preliminarily explored. BMO/ZIS had the best degradation performance with a removal efficiency of 96.52% for RhB, which was 7.02 times and 3.67 times higher than Bi2MoO6 and pure ZnIn2S4, respectively. Achieving the degradation of high concentration RhB with a small amount of photocatalyst.
