Synthesis of Mesoporous Silica Coated Magnetic Microspheres on Large Scale

Abstract:

We present a simple method to synthesize the mesoporous Fe₃O₄@SiO₂via two-step procedure on large scale, and CTAB plays dual role in the sol-gel reaction. First it can prevent the Fe₃O₄ from depositing, ensure to obtain silica homogenouly coated Fe₃O₄. What’s more important, it also act as the template to synthesize the mesoporous Fe₃O₄@SiO₂. In addition, the mesoporous Fe₃O₄@SiO₂ will be potential in application of bioseparation.
