摘要

Oxygen Reduction In article number 2104934, Xiaohua Yang, Long Zhao, Shuhui Sun, Jianming Zhang, and co-workers describe an in-situ silica xerogel synthetic strategy of an Fe-N-C single atom catalyst for the oxygen reduction reaction in metal-air-batteries. The silica xerogel, formed in-situ with the Fe, N and C precursors, encourages the emergence of unique porosity and homogeneous protection to the precursors during pyrolysis, favoring the formation of abundant accessible active sites.
