In this paper, well dispersed AgPd nanoparticles supported on reduced graphene oxide were fabricated by a simple nonnoble metal sacrificial method. Firstly, the Co₃(BO₃)₂ and AgPd nanoparticles were co-deposited on the surface of reduced graphene oxide, then the Co₃(BO₃)₂ was sacrificed by acid etching. Highly dispersed AgPd nanoparticles were obtained by using cobalt as the sacrificial agent to prevent AgPd nanoparticles from aggregation. The obtained catalyst furnish excellent catalytic activity and chemoselectivity for the catalytic transfer hydrogenation of nitroarenes using formic acid and ammonium formate as hydrogen source at room temperature. The homologous aniline derivatives were obtained with high yields.

在本文中，通过简单的非贵金属牺牲方法制备了负载在还原性氧化石墨烯上的分散良好的AgPd纳米粒子。首先，将Co ₃（BO ₃）₂和AgPd纳米颗粒共沉积在还原的氧化石墨烯表面，然后再沉积Co ₃（BO ₃）₂通过酸蚀刻牺牲。通过使用钴作为牺牲剂来防止AgPd纳米粒子聚集，可获得高度分散的AgPd纳米粒子。所获得的催化剂在室温下以甲酸和甲酸铵为氢源为硝基芳烃的催化转移氢化提供优异的催化活性和化学选择性。以高产率获得了同源苯胺衍生物。
