Abstract
Abstract The intelligent construction of non‐noble metal materials that exhibit reversible oxygen reduction reaction (ORR) and oxygen evolution reaction (OER) with bifunctional electrocatalytic performance is greatly coveted in the realm of zinc‐air batteries (ZABs). Herein, a crafted structure‐amorphous MnO 2 lamellae encapsulated covalent triazine polymer‐derived N, S, P co‐doped carbon sphere (A‐MnO 2 /NSPC) is designed using a self‐doped pyrolysis coupled with an in situ encapsulation strategy. The customized A‐MnO 2 /NSPC‐2 demonstrates a superior bifunctional electrocatalytic performance, confirmed by a small Δ E index of 0.64 V for ORR/OER. Experimental investigations, along with density functional…
