质子交换膜燃料电池氮掺杂碳基催化剂研究进展∗

摘要

This article briefly introduces the application and development of nitrogen-doped carbon catalysts for the cathodic oxygen reduction reaction(ORR)in polymer electrolyte membrane fuel cell and summarizes research con-clusions of nitrogen-doped carbon catalysts in recent years.The parameters which affect catalyst activity towards the ORR including nitrogen precursors,metal precursors,metal loadings,carbon precursors and thermal-treatment process are discussed in detail.Meanwhile,the current difficulties in research and future development of nitrogen-doped catalysts for ORR are proposed.%简要介绍了近年来氮掺杂碳基催化剂在质子交换膜燃料电池阴极氧还原方面的应用发展状况，详细总结了最近几年有关氮掺杂碳基催化剂制备及机理方面的研究结果，包括氮源前驱体种类、金属前驱体种类、金属的含量、碳源前驱体种类、热处理工艺等影响催化剂氧还原活性的主要因素，并指出了目前研究中的难点以及未来的发展方向。
