摘要
综述了聚苯胺(PANI)负载纳米金催化剂的制备方法,包括PANI载体的合成及负载纳米金颗粒(AuNPs)的方法,介绍了PANI的不同形貌和AuNPs的不同空间负载位置对AuNPs的稳定性及催化活性的影响,分析了AuNPs吸附和原位还原两种不同负载方式的机理及优缺点,探讨了PANI与负载的AuNPs之间电荷转移和相互作用的机制,并展望了PANI负载纳米金催化剂的发展方向。
The preparation methods of polyaniline(PANI)supported nano-gold catalysts including the synthesis of PANI supports and the loading method of gold nanoparticles(AuNPs)are summerized.The influences of different morphologies of PANI supports and different spatial loading positions of AuNPs on the stability and catalytic activity are introduced.The specific mechanisms,advantages and disadvantages of AuNPs adsorption loading method and in-situ reduction method are compared.The mechanism of charge transfer and interaction between PANI and supported AuNPs is discussed,and finally the development outlook of PANI supported nano-gold catalysts is proposed.
