제목 Controllable Synthesis and Catalytic Activity of Dendritic Fibrous Nanosilica (DFNS)/Gold (Au) Hybrid Nanomaterials
초록 Dendritic fibrous nanosilica (DFNS) with a high degree of porosity, stability, and ease of surface modification is successfully employed as an efficient template to fabricate DFNS/Au hybrid nanomaterials. Au nanodots are initially synthesized by the selective reduction of Au ion by NaBH4 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 also compared.
