摘要： 在碱性条件下,利用十六烷基三甲基溴化铵(CTAB)为结构导向剂,以含氨基有机硅烷与过渡金属离子Co(Ⅱ)形成的配合物Co(Ⅲ)-APTMOS为金属离子前驱体,合成了含金属元素钴的介孔Co-SiO2微球.运用XRD,TEM以及N2-吸附等技术对所制备的产物进行了表征.结果表明,产物为具有高比表面、孔道无序的介孔微球.同时阐述了金属离子以配合物Co-APTMOS形式加入反应体系的优越性.

Abstract: In basic media, millimeter sized mesoporous Co-SiO2 spheres were synthesized successfully through the introduction of Co(Ⅲ)-APTMOScomplex into the reaction mixture with cetyltrimethylammonium bromide(CTAB) as a structural template. The products are characterized by N 2 adsorption, HRTEM, SEM, and ICPtechniques. The results show that the mesoporous Co-SiO2 spheres have a high surface area and disordered pores. Furthermore, the advantage of using Co(Ⅲ)-APTMOScomplex as the source of metal element Co is discussed.
