摘　　要：为了满足激增的全球能源需求并应对环境危机,迫切需要可持续能源技术。燃料电池和金属空气电池以其高能量密度和低污染被视为未来的能源解决方案。特别是锌空气电池,以其高能量密度和安全性而闻名。然而,其性能受到阴极氧还原反应(ORR)电催化剂的限制。利用球磨和热解技术开发了一种新型的非贵金属基电催化剂,该催化剂含有Fe_(3)C/FeP_(2)异质结和Fe-Nx活性位点,展现出优异的ORR性能和稳定性。In order to meet the surging global energy demand and address environmental crises,there is an urgent need for sustainable en-ergy technologies.Fuel cells and metal air batteries are seen as future energy solutions due to their high energy density and low pollution.Especially zinc air batteries are known for their high energy density and safety.However,their performance is limited by cathodic oxygen reduction reaction(ORR)electrocatalysts.A novel non precious metal based electrocatalyst was developed using ball milling and pyrolysis techniques,which contains Fe_(3)C/FeP_(2) heterojunction and Fe-Nx active sites,exhibiting excellent ORR performance and stability.
