| 摘 要： | 以聚苯乙烯为胶晶模板,采用溶胶-凝胶法制备了有序多级孔N/Nd/TiO_2(1),其结构和形貌经SEM,XRD,XPS和N2吸附-脱附表征。研究了1在可见光下催化降解甲基橙的性能。结果表明:1为有序大孔/介孔多级结构,大孔孔道/介孔孔窗呈相互通透三维有序结构,大孔孔道内径约230 nm,介孔孔窗约30 nm,比表面积为125.50 m~2·g~(-1),比孔容为1.124 5 cm~3·g~(-1)。1催化甲基橙的脱色率为42.76%。

| Abstract: | Ordered multistage aperture N/Nd/TiO2(1) was prepared by sol-gel method, using polystyrene latex crystal as the template agent.The structure and morphology were characterized by SEM, XRD, XPS and N2 adsorption-stripping.The photocatalytic performance of 1 on methyl orange under visible light was investigated.The results showed that the morphology of 1 was ordered macroporous/mesoporous structure, macropore pore canals/mesoporous windows present permeable three dimensional ordered structure, the inner diameters of the macroporous pore channels and mesoporous windows were 230 nm and 30 nm, respectively, the surface area was 125.50 m2·g-1 and pore volume was 1.124 5 cm3·g-1.The decolorization rate of methyl orange was 42.76% in the presence of 1. |
