||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.
||Fe3O4@SiO2@TiO2-Co/rGO has the characteristics of good dispersibility, strong adsorption and easy recovery. The Fe3O4@SiO2@TiO2 magnetic photocatalyst not only absorbs in the ultraviolet region but also has weak absorption in the visible region. However,fe3o4-Silicon dioxide-Titanium dioxide-Co and Fe3O4@SiO2@TiO2-Co/rGO magnetic photocatalysts still have strong absorption in the visible region.
