Proton/anion‐exchange membrane fuel cells (PEMFC and AEMFC), generating electricity from the H2 energy with zero‐carbon emission, have become very promising energy conversion devices to meet the increasing energy demand and reduce the dependence on fossil fuels. Currently, platinum (Pt) based materials have proven to be the most efficient electrocatalysts for the oxygen reduction reaction (ORR) at the cathode of the PEMFC and AEMFC. However, the high price and the limited reserve of Pt greatly hinder their industrial applications. Recently, transition metal‐nitrogen‐carbon (M−N−C) based material, as an efficient alternative to replace the precious metal Pt‐based material, has attracted researchers’ attention. Great contributions have been devoted to develop M−N−C based electrocatalysts. This review summarizes recent advances on M−N−C based electrocatalysts used for ORR from the point view of morphology. One‐dimensional (1D), two‐dimensional (2D), three‐dimensional (3D) and multi‐dimensional (MD) M−N−C materials were discussed thoroughly with particular attention on the relationship between the structure and the catalytic activity.

电催化剂形态对氧还原反应的重要性

质子/阴离子交换膜燃料电池(PEMFC和AEMFC),可从H 2发电零碳排放的能源已经成为非常有前途的能源转换设备,可以满足不断增长的能源需求并减少对化石燃料的依赖。目前,已证明铂(Pt)基材料是PEMFC和AEMFC阴极上氧还原反应(ORR)的最有效的电催化剂。然而,Pt的高价格和有限的储备极大地阻碍了其工业应用。最近,过渡金属-氮-碳(MC)材料作为替代贵金属铂基材料的有效替代品已引起研究人员的关注。人们已经为开发基于MC的电催化剂做出了巨大的贡献。这篇综述从形态学的角度总结了用于ORR的基于MC的电催化剂的最新进展。一维(1D),
