Abstract: Au nanoparticles were synthesized by reducing chloroauric acid with oleylamine in 1-butyl-3-methylimidazolium tetrachloroferrate ([Bmim]FeCl4). Their morphology was investigated by TEM, and their catalytic properties on the reduction of 4-nitrophenol by NaBH4 were studied. The results reveal that the size and shape of particles are mostly determined by the molar ratio of [Bmim]FeCl4 to oleylamine. Au nanoparticles change from branched shape to flake one while the ratio increases from 0.5 to 2. Branched nanoparticles show improved catalytic activity compared with flake-shaped nanoparticles.
Key words: nanoparticles, crystal growth, microstructure, [Bmim]FeCl4, atalytic property
摘要: 在1-丁基-3-甲基咪唑四氯化铁盐([Bmim]FeCl4)中用油胺还原AuCl3制备了2种金纳米材料,研究了产物的形貌特征,考察了所制纳米材料催化NaBH4还原对硝基苯酚制备对胺基苯酚的性能. 结果表明,产物形貌主要由[Bmim]FeCl4/油胺摩尔比决定,比值从0.5增至2,金纳米材料从枝状结构转变成花状结构,长径比约为10的棒变为径向长度200 nm的片层;枝状纳米颗粒比花状纳米颗粒的催化性能好.
