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 with unique copper-based active sites render the as-prepared Cu–N/C catalyst with comparable oxygen reduction electrocatalytic activity and superior stability than a zinc–air battery.
