Article Preview

We present a simple method to synthesize the mesoporous Fe3O4@SiO2 via 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.
