本研究旨在开发基于海水的高性能氧还原反应（ORR）电催化剂，这对于可再生能源的存储和转换具有重要意义。目前，基于铁的衍生物被氮掺杂的碳包覆，是典型的代表。然而，揭示氮构型对ORR活性和耐氯性的机制仍然是一个巨大挑战。

在质子交换膜燃料电池(PEMFC)中，Pt是氧还原反应(ORR)活性最高的材料。然而，贵金属Pt储量稀少和价格昂贵，减少材料中Pt含量是减少其使用的最直接的策略，但这通常伴随着活性位点数量的减少或发生团聚。Pt与其他后过渡金属合金化提高了Pt的活性， ...

过氧化尿素(CO(NH2)2•H2O2)作为尿素的衍生物，已广泛应用于制药、农业、纺纱、日常化工等。CO(NH2)2•H2O2的工业生产主要依赖于尿素和H2O2这两种反应物。其中，通过碳源(CO2)和氮源(N2、NO、NO2−、NO3−)耦合高效电催化剂，可以在电化学条件下通过电催化C-N偶联反应有效地生成尿素。同时，利用高效电催化剂和活性OOH中间体的适当 ...
