| 摘 要： | 以十六烷基三甲基溴化铵(CTAB)为模板剂,钛酸正四丁酯(TBOT)为钛源,异丙醇为溶剂,通过醇热法合成介孔TiO_2,用N_2吸附-脱附、XRD、TEM等技术对合成样品进行了表征。以亚甲基蓝的降解为模型反应,对介孔TiO_2催化性能进行评价并与商品DegussaP-25比较。实验结果表明,比表面积为248.8 m~2·g~(-1),孔径为4.92 nm的锐钛矿晶型介孔TiO_2具有很高的催化活性。

| Abstract: | Mesoporous titania was preparated by alcohol-heating method using cetyltrimethyl ammonium bromide(CTAB) as a template,tetra-n-butyl titanate(TBOT) as titanium source and anhydrous ethanol as a solvent.The products were characterized by N_2 adsorption-desorption,XRD and TEM.The catalytic activity of mesoporous titania was investigated by the photocatalytic degradation of methylene blue and compared with Degussa P-25.The results show that the anatase TiO_2 powder with the specific surface area of 248.8 m~2/g,... |
