We propose a high performance bifunctional electrocatalyst consists of cobalt phosphosulfide (CoPS) nanoparticles encapsulated with S, P, N-tri-doped carbon (CoPS@SPNC) derived from zeolitic imidazolate framework-67 (ZIF-67) and applicate it to the Zinc-air battery (ZAB) as a electrode catalyst for the oxygen reduction reaction (ORR) and oxygen evolution reaction (OER).
