采用溶胶 凝胶法制备了TiO2 纳米溶胶 ,用浸渍法将其负载于颗粒形活性炭的表面制成TiO2 负载膜 ,利用SEM ,EDS和XRD等手段对膜的形貌、均匀性及晶型等进行了表征 ,并通过甲基橙水溶液的光催化降解反应考察了该负载膜的光催化活性
The TiO2 nano-sol was prepared by sol-gel method and impregnated onto the surface of granular activated carbon to form TiO2 supported film. The morphology, uniformity and crystal form of the film were characterized by SEM, EDS and XRD The characterization was carried out and the photocatalytic activity of the supported membrane was investigated by photocatalytic degradation of methyl orange aqueous solution
