摘要
聚多巴胺是一种新型的贵金属催化剂载体,具有邻苯二酚、氨基和亚氨基等官能团,可以在无还原剂的条件下直接将贵金属离子还原为贵金属纳米粒子。概括了聚多巴胺的聚合方法、聚合机理以及形貌控制方法。从催化剂制备和应用方面介绍了聚多巴胺负载贵金属催化剂的研究进展,分析了聚多巴胺负载贵金属催化剂的催化作用机制,并展望了聚多巴胺负载贵金属催化剂的发展和应用前景。
Polydopamine is a novel carrier of noble metal catalyst,which has functional groups such as catechol group,amino group and imine group.It can directly reduce noble metal ions to noble metal nanoparticles without reducing agent.In this paper,the preparation method,polymerization mechanism and morphology control strategy of polydopamine are summarized.Resent progress of polydopamine supported noble metal catalyst is introduced from aspects of catalyst preparation and application.The catalytic mechanism of polydopamine supported noble metal catalysts is analyzed,and their future developments and potential applications are prospected.
