分子筛负载硫化镉光催化降解罗丹明B的研究

摘要

CdS Loaded on SiO, molecular sieve is prepared via a wet chemical method, CdS-SiO2 for photocatalytic degradation of organic pollutant Rhodamine B, compared to that of pure CdS, the CdS loaded on the molecular sieve shows a higher photocatalytic activity in a degradation process of Rhodamine B aqueous solution under visible light irradiation.%采用湿化学法制备了分子筛多孔二氧化硅负载硫化镉光催化材料CdS-SiO2,用于可见光降解有机污染物罗丹明B.结果表明,相比单相的硫化镉,分子筛负载的硫化镉表现出更高的光催化效率,且光降解后催化剂沉淀回收后仍可表现出较高的光催化降解能力.
