Bimetallic conjugated microporous polymer derived B,N-doped porous carbon wrapped Co3Fe7 alloy composite as a bifunctional oxygen electrocatalyst for a breathing Zn–air battery

A B, N-codoped carbon-based bifunctional oxygen electrocatalyst was prepared. This presented outstanding catalytic activity for electrochemical oxygen reduction and evolution reactions and could be used as the catalyst for a breathing Zn–air battery.
