摘要

•Solvent mediation and zinc fencing dually regulated cathode catalyst efficacy.•Methanol dosage mediated the particle size of bimetallic ZIFs over a wide range.•Zinc fence dispersed hybrid cobalt active sites onto the porous carbon skeleton.•Coexistence of micro/mesopores ensured active site exposure and mass transfer.•Optimized cobalt active sites embedded porous carbon BES exhibited 2057 mW m−2.
