摘要
采用溶胶-凝胶法在十六烷基三甲基溴化铵(CTAB)辅助下制备了TiO2光催化剂,以甲基橙为模拟有机污染物对催化剂的光催化脱色性能进行了考察。用BET比表面对所制备的催化剂进行了表征,结果表明当nCTAB∶nTBOT比为1∶4,锻烧温度为450℃时,制备的TiO2为介孔;试验制备的TiO2对甲基橙光催化脱色活性是市售TiO2的2倍。
Mesopomus TiO2 was prepared by a sol-gel method with the assistance of eetyl trimethyl ammo- nium bromide （CTAB）. Then the activity of the photoeatalyst so produced for photocatalytic decolorization of methyl orange （MO） solution was evaluated, and the photocatalyst was characterized with BET specific surface. The results indicate that with the ratio of nCTAB to nTBOT at 1 ： 4 and calcination temperature at 450℃, mesopomus TiO2 can be obtained. In addition, the activity of TiO2 prepared in our experiments for photocatalytic decolorization of methyl orange is two times that of the TiO2 commercially available.
