构建氧配位Co单原子电催化剂，促进尿素和过氧化尿素生产
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 ...

pH-电场耦合理论提供单原子酸/碱ORR新认识
金属-氮-碳（M-N-C）单原子催化剂被认为是高效的铂基催化剂替代品。过去，单原子催化剂在不同pH环境下的活性和选择性机制存在争议。本研究通过分析超过100种M-N-C结构，成功开发了单原子催化剂的pH-电场耦合新模型。该模型揭示了氧还原反应（ORR ...

如何像均相催化剂一样调节多相催化剂ORR活性
研究背景 现阶段质子交换膜燃料电池（PEMFCs）发展瓶颈在于阴极氧还原反应 (ORR)的缓慢动力学导致严重依赖贵金属Pt基催化剂加速反应进程。然而Pt催化剂的高成本和低储量限制大规模应用。具有M-N4中心的M-N-C基催化剂，例如M-N4大环配合物和 M-N 掺杂碳 (M-N-C) ...
