제목 Facile Synthesis and Catalytic Application of Spherical Nanoparticles with a Porous Silica Shell and Multiple Au Nanodots as the Core
초록 Highly spherical nanoparticles with a core comprising multiple gold (Au) nanodots and a silica shell (multi-Au@SiO2 NPs) were successfully synthesized through a reverse (water-in-oil) microemulsion-based method. Multiple Au nanodots with a maximum diameter of ~5 nm could be encapsulated within a silica matrix during the growth process. Further, the multi-Au@SiO2 NPs could be softly etched by thermal treatments to give multiple Au nanodots core–mesoporous silica shell nanoparticles (multi-Au@mesoporous-SiO2 NPs). The multi-Au@mesoporous-SiO2 NPs showed much higher catalytic activity in the reduction of 4-aminophenol compared to other Au core-silica shell nanoparticles.
