Abstract To realize the practical application of rechargeable Zn–Air batteries (ZABs), it is imperative to develop a non‐noble metal‐based electrocatalyst with high electrochemical performance for oxygen reduction reaction (ORR) and evolution (OER). Herein, Ni‐doped Co 9 S 8 nanoparticles dispersed on an inverse opal‐structured N, co‐doped carbon matrix (IO─Ni x 9‐x @NSC) as bifunctional presented. The unique 3D porous structure, arranged in opal pattern, provides large active surface area. Also, conductive substrate ensures homogeneous dispersion Ni nanocrystals, preventing aggregation increasing exposure sites. introduction heteroatom dopants into structure generates defect sites enhances polarity, thereby improving electrocatalytic alkaline solutions. Consequently, IO─Ni @NSC shows excellent activity half‐wave potential 0.926 V ORR low overpotential 289 mV at 10 mA cm −2 OER. Moreover, ZAB assembled prepared exhibits higher specific capacity (768 mAh g Zn −1 ), peak power density (180.2 mW outstanding stability (over 160 h) compared precious electrocatalyst.
