Controllable Synthesis and Application of Dendritic Fibrous Nanosilica (DFNS)/Gold (Au) Hybrid Nanomaterials |
| 초록 |
Dendritic fibrous nanosilica (DFNS) with a high surface area is successfully employed as a template to synthesize DFNS/Au hybrid nanomaterials. Au nanodots are initially synthesized by the selective reduction of Au ion on the surface of the DFNS after surface modification to form DFNS/Au dots. A seed-mediated growth method is used to controllably grow Au nanoparticles on the DFNS/Au dots to generate DFNS core-Au NPs shell nanoparticles (DFNS/Au NPs) and DFNS core–Au layer shell nanoparticles (DFNS/Au layers). The catalytic activities of DFNS/Au NPs and DFNS/Au layers in the 4-nitrophenol reduction reaction are compared. |
