摘要(Abstract)：

制备高效、稳定的析氧反应(OER)电催化剂是工业制氢的关键所在。使用尿素作为造孔剂和活性C/N源，基于纳米级柯肯达尔效应，通过高温烧结制备了纳米多孔合金NiFeCoMgCN,并分析了其作为电极的电催化性能。结果表明：在1 M KOH溶液中，NiFeCoMgCN电极在10 mA·cm~(-2)下的过电位为199 mV,Tafel斜率为41.7 mV·dec~(-1),优于IrO_2/Ni foam电极(10 mA·cm~(-2)下的过电位为215 mV,Tafel斜率为76.3 mV·dec~(-1)),并且在1 A·cm~(-2)的大电流密度下能够持续工作至少100 h。NiFeCoMgCN电极优异的催化活性归功于其连续的纳米多孔结构和本质活性的提高。
