Mesoporous metal oxide/silica composites with photocatalytic activity and magnetic response

摘要: Abstract In this work, a novel class of mesoporous metal oxide/silica composites was prepared. Both ZnO and magnetite (Fe3O4) nanoparticles were embedded within the silica architecture. The solids display high surface area, narrow pore size distribution regular array hexagonal channels with long range ordering. All materials tested for photodegradation Rhodamine B catalytic performance compared analogous exclusively bearing in framework. present good photocatalytic magnetic response. best catalyst containing 15 wt% 5 wt% Fe3O4 particle loading, displays higher turnover number than unstructured commercial nanopowder can be easily separated from reaction mixture by simply applying field as weak one generated common stirring bar.
