It is necessary to correctly research and synthesize efficient inexpensive catalysts achieve reversible oxygen reduction reaction (ORR) evolution (OER), which also a prerequisite for zinc–air batteries (ZABs). However, it still huge challenge manufacture electrocatalysts with durable high electrocatalytic performance from biomass. Here, convenient method of delignification was used transform natural balsa wood into layered porous carbon material, FeCo alloy supported on N, S-doped wood-based aerogel (FeCo@NS-CA) as the cathode in rechargeable flow ZAB. The obtained FeCo@NS-CA lamellar architecture exhibits superior bifunctional electrocatalysis, including excellent electrochemical activities stabilities. For ORR, relative hydrogen electrode, onset potential 0.97 V, half-wave 0.85 consistent commercial Pt/C. OER, an overpotential 450 mV, very similar benchmark RuO2. could be owing carrier interaction between co-doped N S. Moreover, air ZAB assembled catalyst at current density 10 mA cm–2; power 140 mW cm–2, specific capacitance 760 h gZn–1, remarkable long-term stability 400 better than Pt/C + This lays foundation transforming abundant biomass resources environmental protection materials energy-related applications.
