Boosting the activity and stabilityviasynergistic catalysis of Co nanoparticles and MoC to construct a bifunctional electrocatalyst for high-performance and long-life rechargeable zinc–air batteries

We report a ZIF-67-derived multiphase doped carbon ORR/OER catalyst (Co/MoC-NC) with the synergistic catalysis of Co and MoC. ZABs assembled with Co/MoC-NC demonstrate an excellent power density (215.36 mW cm −2 ) and great durability (more than 300 h).
