Multifunctional magnetic core-shell dendritic mesoporous silica nanospheres decorated with tiny Ag nanoparticles as a highly active heterogeneous catalyst

- A multifunctional magnetic core-shell dendritic silica nanocatalyst was successfully fabricated by an oil-water biphase stratification coating strategy.
- The magnetic core-shell dendritic silica nanomaterials Fe3O4@SiO2@Dendritic-SiO2 were chosen as the catalyst's support for the first time.
- The as-synthesized nanocatalyst exhibited excellent catalytic activity and reusability due to easy accessibility of active sites and superparamagnetism.
- The novel catalyst could be conveniently recovered by magnetic separation from the reaction system.
