Metal-free carbon electrocatalysts, such as heteroatom and defective doped carbons, are important for various reactions, including oxygen reduction reaction (ORR) and hydrogen evolution reaction (HER). In this issue of Chem, Yao and co-workers report a targeted synthesis approach to specific carbon defects, including adjacent carbon pentagons and divacancy defects attractive for ORR and HER, respectively.

靶向缺陷合成可改善电催化性能

不含金属的碳电催化剂，例如杂原子和有缺陷的掺杂碳，对于包括氧还原反应（ORR）和析氢反应（HER）在内的各种反应都很重要。在本期《化学》杂志上，姚和同事报告了针对特定碳缺陷的针对性合成方法，这些缺陷包括相邻的碳五边形和分别对ORR和HER有吸引力的空位缺陷。
