【摘要】 分散型铂纳米微粒和负载型铂纳米微粒都是重要的催化剂。制备尺度可控、粒度分布均一的铂纳米微粒,对提高其催化活性和选择性,以及延长其使用寿命具有重要的意义。本文介绍了分散型和负载型铂纳米微粒常用的制备方法,讨论了各方法的制备原理及其优缺点。更多还原

【Abstract】 Both of dispersed and supported Pt nanoparticals are important catalysts.Many methods both of chemical and physical are developed to prepare nano-Pt, but there is still a focus on the preparation of nano-Pt,with uniform-sized,high activity,good selectivity and long life-span.This paper concentrated on the progress in preparation of nano-Pt,the principle,the advantages and disadvantages of each preparing method were discussed.更多还原
