摘要：

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