Fuel cells/zinc–air cells represent a transformative technology for clean energy conversion, offering substantial environmental benefits and exceptional theoretical efficiency. However, the high cost limited durability of platinum-based catalysts sluggish oxygen reduction reaction (ORR) at cathode severely restrict their scalability practical application. To address these critical challenges, this study explores groundbreaking approach to developing ORR with enhanced performance reduced costs. We present novel Pd3Cu alloy, innovatively modified N-doped carbon aerogels, synthesized via simple self-assembly freeze-drying method. The three-dimensional aerogel-based porous structures provide diffusion channels molecules, excellent electrical conductivity, abundant sites. Pd3Cu@2NC-20% aerogel exhibits remarkable enhancement in activity, achieving half-wave potential 0.925 V, limiting current density 6.12 mA/cm2, long-term stability. Density functional theory (DFT) calculations reveal that electrons tend transfer from Pd atoms neighboring *O, leading an increase negative charge around *O. This, turn, weakens interaction between catalyst surface *O optimizes elementary steps process.
