摘要/Abstract

摘要： 以十六烷基三甲基溴化铵、十二烷基硫酸钠和P123三种表面活性剂为共模板剂合成了含钒介孔空心球, 研究了钒含量及反应条件对空心球形成的影响. 结果表明: 当n(V)/n(Si)低于0.05时不能形成空心球, 而n(V)/n(Si)过大时, 大部分钒在材料中以氧化物形式出现, 合适的n(V)/n(Si)为0.1. 最佳反应条件为pH值5.0, 45℃反应2 h. 产物结构规整, 且对苯乙烯过氧化氢选择氧化反应有着良好的催化性能.

Abstract: Vanadium-containing mesoporous silica with hollow spherical morphology was successfully synthesized by using CTAB, SDS and P123 as co-template. The influences of vanadium content and reaction conditions on the formation of the materials were also studied. Results indicated that the hollow spheres could not be shaped as molar ratio of V to Si was lower than 0.05 while excess vanadium content led large amount of vanadium oxides existed in the materials. The adequate molar ratio of V to Si was 0.1. The optimal synthesis conditions were reacted at 45℃ for 2 h under pH value of 5. The products with regular structure and morphology exhibited high catalytic activity on the selective oxidation of styrene by hydrogen peroxide.

Key words: vanadium, mesoprous materials, hollow spheres
