CoFe formic-acid framework derived S, N co-doped carbon nanotube composites decorated with a bimetallic sulfide as a bifunctional electrocatalyst for rechargeable zinc–air batteries

A S, N co-doped carbon nanotube ORR/OER electrocatalyst loaded with a cobalt–iron alloy and Co 8 FeS 8 nanoparticles was synthesized using a one-step pyrolysis method.
