FeNiP nanoparticle/N,P dual-doped carbon composite as a trifunctional catalyst towards high-performance zinc–air batteries and overall water electrolysis

A novel catalyst with FeNiP nanoparticles embedded in an N,P dual-doped carbon matrix was prepared. It exhibits low overpotentials for both the ORR and OER. The rechargeable zinc–air batteries assembled with this catalyst exhibited excellent performances.
