Abstract The development of efficient and low‐cost catalysts for cathodic oxygen reduction reaction (ORR) in Zn‐air battery (ZAB) is a key factor reducing costs achieving industrialization. Here, novel segregated CoNiPt alloy embedded N‐doped porous carbon with nanoflowers (NFs)‐like hierarchy structure synthesized through pyrolyzing Hofmann‐type metal‐organic frameworks (MOFs). unique hierarchical NFs exposes more active sites facilitates the transportation intermediates, thus accelerating kinetics. Impressively, resulting 15% CoNiPt@C catalyst exhibits outstanding alkaline ORR activity half‐wave potential 0.93 V, its mass 7.5 times higher than that commercial Pt/C catalyst, surpassing state‐of‐the‐art noble metal‐based catalysts. Furthermore, assembled CoNiPt@C+RuO2 ZAB demonstrates maximum power density 172 mW cm −2 , which superior to Pt/C+RuO2 ZAB. Experimental results reveal intrinsic attributed synergistic interaction between defects pyrrolic/graphitic N species, optimizes adsorption energy intermediate species process greatly enhances catalytic activity. This work provides practical feasible strategy synthesizing cost‐effective by optimizing electronic MOF‐derived
