COOH-SiO2@Fe3O4 12-17nm

Carboxyl functionalized mesoporous silica can form a composite material with iron (III) oxide (Fe3O4) to encapsulate Fe3O4 inside the mesoporous silica.Carboxyl modified mesoporous silica has a large pore structure and carboxyl functional groups, which can provide a good loading and surface modification platform. Fe3O4 is a magnetic material with potential applications in biomedical and magnetic materials fields.
