Hollow mesoporous nanosilica has received much attention from researchers due to its exceptional properties with high specific surface area and large pore channels. Morphologically unique silica nanostructures can be employed as effective supports to develop silica–metal nanohybrid, which are highly applicable in a vast number of areas. Herein, hollow fibrous nanosilica (HFNS) with high specific surface area, fiber-like mesoporous structures in the inner and outer shells, and large pore sizes are successfully used as a template to embed metallic nanoparticles to afford HFNS/M hybrid nanomaterials. This process is carried out via selective reduction of metallic ions onto HFNS after surface modification by an amine group.For comparison, dendritic fibrous nanosilica (DFNS) is also used as a support to prepare DFNS/M nanostructures in the same manner. The catalytic activities of HFNS/M and DFNS/M hybrid nanosystem in organic reduction reactions were evaluated. |
