摘　　要：采用微波法合成BiOI光催化剂,并研究了BiOI光催化剂的制备条件及其光催化降解有机污染物的能力,以Bi(NO3)3·5H2O和KI为主要原料,乙二醇与水为溶剂,利用微波法的反应速率快,效率高的特点,合成BiOI光催化剂。在紫外光条件下,以甲基橙溶液为模型污染物,研究其光催化降解性能。紫外光照射条件下得到了对甲基橙具有良好脱色效果的光催化材料。Using microwave heating method, BiOI powder photocatalyst was prepared and their photocatalytic properties were examined. The dissertation mainly included BiOI photocatalyst which was prepared by microwave irradiation method was an assisted -synthesis using Bi （NO3 ）3 ·5H2O and KI as the starting raw material, glycol and water as the solvent. The photocatalytic activities of the samples were estimated from the photodegradation of methyl orange （MO） under irradiation with ultraviolet light. The result showed that BiOI had good catalytic activities towards the degradation of MO under ultraviolet light irradiation.
