摘　　要：通过凝胶-溶胶法制备了Bi2O3-MgO复合材料,用可见光降解罗丹明B,考察了n(Bi)∶n(Mg)、反应温度、活化时间以及煅烧温度等因素对Bi2O3-Mg O光催化性能的影响,并得出最佳制备条件:n(Bi)∶n(Mg)=2,反应温度90℃、活化时间15 h,煅烧温度500℃。Bi2O3-MgO composite material has been prepared by sol-gel method. The effects of the factors , includ-ing n（Bi）∶n（Mg）,reaction temperature,activation time,calcination temperature,etc.,on the photocatalytic activity of Bi2O3-MgO are investigated by the visible light degradation of Rhodamine B. The optimal preparation conditions obtained are as follows：n（Bi）∶n（Mg） is 2,reaction temperature 90℃,activation time 15 h and calcination tempera-ture 500℃.
