以钛酸丁酯为原料,竹炭为载体,采用溶胶-凝胶法、浸渍法,通过常压干燥制备出TiO_2气凝胶,实现了竹炭与TiO2气凝胶的复配。采用XRD、SEM及此紫外可见分光光计对制得的负载:氧化钛气凝胶竹炭复合材料进行表征。结果表明:800℃热处理后的TiO_2气凝胶晶型为锐钛矿结构,形貌显示其为球状,此温度下复合材料的性能最为优越,其对亚甲基蓝的静态吸附催化能力高于同温度下活化的竹炭及气凝胶。 Using butyl titanate as raw material and bamboo charcoal as carrier, TiO 2 airgel was prepared by sol-gel method and impregnation method and dried at atmospheric pressure to achieve the compounding of bamboo charcoal and TiO 2 airgel. The XRD, SEM and UV-Vis spectrophotometer were used to characterize the load: titanium oxide airgel bamboo charcoal composites. The results show that the crystal structure of the TiO_2 airgel after heat treatment at 800 ℃ is anatase, and the morphology is spherical. Under this temperature, the composites have the best performance. The catalytic activity of methylene blue on static adsorption is higher than that of the same temperature Activated charcoal and airgel.
