金磁微粒的制备及其催化性能
Preparation and catalytic performance of gold magnetic particles
摘要
Abstract
In this experiment,the Fe3O4 nanoparticles were prepared using hydrothermal method.The gold magnetic particles (Fe3O4@Au)were formed by the Fe3O4 nanoparticles combined with gold nanoparticles using self-assembly method based on the surface amino groups.Fe3O4@Au was characterized based on the optimization of process.The resuhs showed that gold nanoparticles prepared by grape skin extract with 1％ concentration and the average particle size were 7 nm.The Fe3O4 functionalized with amino groups could be loaded with gold nanoparticles,the optimum process combination was as follows:the addition of Fe3O4 suspension was 2 mL,the temperature was 60 ℃,and the time was 60 min.Fe3O4@Au,whose saturation magnetization was 61 emu/g,showed strong catalytic properties.关键词
