摘要

采用微波溶剂热法、溶剂热法和共沉淀法三种方法合成碘氧化铋(BiOI)光催化剂,并对其进行了性能表征;以罗丹明B(RhB)为目标污染物,进行可见光光降解性能测试。研究结果表明,共沉淀法合成的BiOI结晶性最好,但溶剂热法合成的材料比表面积最大,降解性能最好,可见光照射60min后,对40mg/L的RhB溶液的降解率达96%。

Abstract

Bismuth iodide (BiOI) photocatalyst was synthesized by microwave solvothermal method,solvothermal method and coprecipitation method,and characterized.Methyl orange was used as the target pollutant to test the photodegradation performance under visible light.The results shown that the BiOI synthesized by coprecipitation method had the best crystallinity,but the material synthesized by solvent method had the largest specific surface area and the best degradability.After visible light irradiation on 60min,the degradation rate of BiOI to rhodamine b solution of 40mg/L can reach 96%.
