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200nm的片层;枝状纳米颗粒比花状纳米颗粒的催化性能好. Two gold nanomaterials were prepared by reduction of AuCl3 with 1-butyl-3-methylimidazolium chloride ([Bmim] FeCl4) using oleylamine. The morphologies of the products were investigated. The effects of the prepared nanomaterials Catalytic reduction of p-nitrophenol by NaBH4 to p-aminophenol showed that the morphology of the product was mainly determined by [Bmim] FeCl4 / oleylamine molar ratio, the ratio increased from 0.5 to 2, and the transition from dendritic structure to The flower-like structure, the rod with an aspect ratio of about 10, became a sheet with a radial length of 200 nm; the dendritic nanoparticles had better catalytic properties than the flower-like nanoparticles.
