In article number 1700740, Yanyu Liang, Junhong Chen, and co‐workers report a novel copper‐based oxygen reduction electrocatalyst (Cu–N/C) facilely fabricated from copper‐doped ZIF‐8. The introduction of copper leads to not only a high‐surface‐area hierarchical structure, but also a unique hybrid coordination configuration of Cu0–Cu2+–N sites. Compared with commercial Pt/C, such highly open structures...
A transition‐metal–nitrogen/carbon (TM–N/C, TM = Fe, Co, Ni, etc.) system is a popular, nonprecious‐metal oxygen reduction reaction (ORR) electrocatalyst for fuel cell and metal–air battery applications. However, there remains a lack of comprehensive understanding about the ORR electrocatalytic mechanism on these catalysts, especially the roles of different forms of metal species on electrocatalytic...
