Abstract
氧还原反应(ORR)是燃料电池和金属-空气电池等各种能源转换器件中重要的半反应. 由于ORR的动力学缓慢, 需要开发高活性电催化剂来替代常用的贵金属铂基催化剂. Fe-N-C催化剂被认为是最有前景的材料, 其丰富的活性位点可以降低含氧中间体的能垒. 在这篇综述中,我们详细总结了Fe-N-C催化剂在理论和实验研究方面的最新研究进展. 首先, 概述了基于Fe-N-C催化剂的电催化ORR的反应机理. 然后, 对Fe-N-C催化剂的设计策略和活性位点进行了分类. 接下来, 讨论了活性位点与催化性能之间的关系. 介绍了Fe-N-C催化剂在燃料电池和锌空气电池中的应用现状. 最后, 进一步提出了Fe-N-C催化剂在可控合成、机理研究和能源器件应用方面面临的挑战和机遇.
