Abstract：
Polyaniline-supported metal nanoparticles (M@PANIs) have been widely employed as catalysts for organic reactions. Traditionally, the catalytic activities of the materials can be improved by introducing functional groups onto the aniline monomers, but it may enhance the catalyst cost and reduce the production yield of the material. This work reports a new strategy for improving the catalytic activity of M@PANIs. It was found that induced by visible light in the presence of a polymeric carbon nitride catalyst and copper dopant, the oxidative polymerization of simple aniline occurred slowly and orderly to produce the copper-doped polyaniline nanotubes. The unique tubular structure protected the catalytically active Cu(I) inside and endowed even more sufficient contact of the catalytic sites with reactants so that the material exhibited excellent catalytic performances in C-N coupling reactions.
摘要：
聚苯胺负载的金属纳米颗粒（M@PANIs）已广泛用作有机反应的催化剂。传统上,可以通过在苯胺单体上引入官能团来提高材料的催化活性，但它可能会提高催化剂成本并降低材料的产量。这项工作报告了一种提高M@PANIs催化活性的新策略。发现在聚合氮化碳催化剂和铜掺杂剂存在下由可见光诱导，简单苯胺的氧化聚合缓慢而有序地发生，生成铜掺杂的聚苯胺纳米管。独特的管状结构保护了内部的催化活性Cu（I），并使催化位点与反应物的接触更加充分，从而使材料在C-N偶联反应中表现出优异的催化性能。
