通过两种方法合成了聚苯胺/钯纳米粒子。结果表明，直接还原法是一种简单易行的制备小粒径（2-7 nm）、分散性好的聚苯胺/Pd纳米粒子的方法。另一方面，开发了模板方法以提供获得具有高Pd密度的小且良好分散的纳米颗粒（1-4 nm，平均直径= 2.4nm）的通用途径，这是由于在聚苯胺上的Pd（II）物质预组织成相应的d，π-共辄络合物。由此获得的纳米粒子作为一个有效的氧化还原催化剂的氧化偶联反应的2，6-二叔丁基苯酚。
Polyaniline/Pd nanoparticles were synthesized through two approaches. Direct reduction approach was revealed to be a simple method to prepare small (2-7 nm) and dispersed polyaniline/Pd nanoparticles via reduction with sodium borohydride. On the other hand, template approach was developed to provide a versatile route to small and well-dispersed nanoparticles (1-4 nm, average diameter =2.4 nm) with high Pd density due to pre-organization of Pd(ll) species on polyaniline into the corresponding d,π-conjugated complex. Thus-obtained nanoparticles worked as an efficient redox catalyst for oxidative coupling reaction of 2,6-di-t-butylphenol.
