摘　　要：以钠基膨润土为载体,采用水热合成法制备膨润土负载Pb Sn O3光催化剂.以亚甲基蓝溶液为目标降解物,在自然光照条件下,研究膨润土负载Pb Sn O3光催化剂对亚甲基蓝溶液的脱色性能.结果表明:膨润土负载Pb Sn O3光催化剂对亚甲基蓝溶液有良好的脱色效果,且具有良好的再生性能.当催化剂浓度为50 mg/L,负载比为5%,光照时间为12 min时,脱色率达到95%以上.PbSnO3/ bentonite compounds were synthesized by hydrothermal method and their photocatalytic activities for the degradation of methylene blue were investigated under the irradiation of sun light. The results indicated that the decolourization rate could reach over 95% when the loading contents were 5%,the amount of the photocatalysts was 50 mg / L and the reaction time was 12 min.
