Morphologically unique silica nanoparticles can be used as effective templates to prepare hybrid materials, which are highly applicable in a variety of areas. Herein, dendritic fibrous nanosilica (DFNS) with low density, high stability and permanent porosity is successfully employed as a template to grow gold nanoparticles and/or zinc-based coordination polymer particles to fabricate DFNS-based hybrid nanomaterials. Au nanodots are initially anchored on the surface of the DFNS through the selective reduction of Au ions to form DFNS/Au dots. The DFNS is subsequently employed as an efficient template to grow Zn-CPPs via solvothermal process, and this leads to the formation of DFNS@Zn-CPPs core-shell nanohybrids. For next step, the DFNS-based derived materials, i.e., DFNS@ZnO and DFNS/Au dots@TiO2 are also fabricated. The obtained hybrid nanomaterials exhibit an enhancement of catalytic acyivity. |
