Carbon nanotubes (CNTs) are corrosion resistant supports for electrochemical applications. A surface functionalization of CNTs prior to pyrolysis enables improved interaction with carbon frames hosting FeN4 moieties: higher site densities and turn‐over frequencies are reached. Together with the good cycling stability during accelerated stress tests, this makes Fe–N–C catalysts of interest for integration in proton‐exchange fuel cells (PEFCs). More details can be found in article number 2000433 by Ulrike I. Kramm and co‐workers.

表面功能化对燃料电池应用中Fe–N–C催化剂内在性能的影响

碳纳米管(CNT)是用于电化学应用的耐腐蚀载体。在热解之前,CNT的表面功能化可以改善与承载FeN 4部分的碳框架的相互作用:达到更高的位点密度和翻转频率。再加上加速应力测试期间良好的循环稳定性,这使得Fe–N–C催化剂成为质子交换燃料电池(PEFCs)集成的关注对象。可以在Ulrike I. Kramm及其同事的文章编号2000433中找到更多详细信息。
