The sluggish kinetics and side reactions of the oxygen reduction reaction have impeded deployment of proton-exchange-membrane fuel cells. A recent article (Xie et al.) introduces an efficient nonprecious metal catalyst (Fe₂N₆) that enhances the kinetics of 4-electron O₂ reduction by more than seven times compared with that of the well-documented single-site FeN₄ catalysts.

双核铁催化剂大大提高了ORR动力学

氧还原反应的缓慢动力学和副反应阻碍了质子交换膜燃料电池的部署。最近的一篇文章（谢等人。）引入了一种有效的非贵重金属催化剂（FE ₂ Ñ ₆）增强4-电子的O动力学₂通过与证据充分的单活性中心芬相比七倍以上还原₄催化剂。
