The development of platinum group metal-free catalysts for the oxygen reduction reaction (ORR) is critical to advancing sustainable energy conversion technologies. Manganese (Mn)-based catalysts, known their reduced toxicity and promising durability, have traditionally exhibited lower ORR activity compared state-of-the-art iron-nitrogen-carbon (Fe-N-C) catalysts. In this study, a highly efficient Mn-N-C-S catalyst presented, engineered through sulfur-mediated high-shell coordinated doping strategy, that markedly enhances stability. achieves record-high half-wave potential 0.94 V in alkaline media, among highest values reported Mn-based Additionally, acidic it exhibits 0.80 V, placing top-performing M-N-C also demonstrates high peak power density 0.82 W cm-2 H2-O2 fuel cells 0.264 Zn-air batteries, outperforming previously Both experimental findings theoretical computations suggest S-doping can increase spin Mn sites, strengthen Mn-N bonds, thereby improve durability Mn-N4 sites. This work underscores effectiveness sulfur paving way deployment cathodes metal-air batteries.
