摘要
以高分子微凝胶为模板,在中性水溶液中催化硅前体原位生成SiO2,形成的有机-无机杂化粒子具有模板分子的多级有序结构、多孔的表面性能及带电性。控制硅前体(TMOS)的用量,可以控制杂化粒子的比表面积和带电性,在载体材料、催化以及分离纯化等方面具有很好的应用前景。
Polymer microgel was used as template, which catalyzed SiO2 depositing in situ in neutral aqueous solution, and the organic-inorganic hybrid particles formed with hierarchical, porous structure and positive charge. By controlling the amount of silica precusor, BET surface areas and charge properties of hybrid particles could be finely controlled, which provided more evidences for the potential application in carrier, catalysis, separation, purification, etc.
