通过改性溶胶—凝胶法合成MnO2-TiO2多孔纳米复合材料,用XRD和SEM对制备的MnO2-TiO2复合纳米材料进行了表征.进一步研究了MnO2-TiO2对茜素红和甲基橙混合染料的光催化性能.用可见分光光度计测量混合染料的吸光度,计算光催化降解率,当茜素红和甲基橙初始浓度为25 mg/L,MnO2-TiO2的含量为0.5 g/L,混合染料的光催化降解率达95％.

Porous nanocomposites of MnO2-TiO2 were synthesized by the modified sol-gel method. MnO2-TiO2 composite nanomaterials were characterized by XRD and SEM. The photocatalytic performance of MnO2-TiO2 for a mixture of alizarin red and methyl orange was further studied. The photocatalytic degradation rate was calculated using absorbance of mixed dye was measured by visible light spectrophotometer. The photocatalytic degradation rate of the mixed dye was 95%, when the initial concentration of a mixture of alizarin red and methyl ...
