摘要(Abstract)：

采用两步水热法制备了CoFe/Ni(OH)_2/NF催化电极。利用X射线衍射仪(XRD)、X光电子能谱仪(XPS)、扫描电镜(SEM)和透射电镜(TEM)对CoFe/Ni(OH)_2/NF催化电极的物相、组成和形貌进行表征。在1 mol/L KOH电解液中对电极的电催化析氧反应(OER)、析氢反应(HER)和全解水性能进行了测试。结果表明：CoFe/Ni(OH)_2/NF电极为三维核壳结构，在OER和HER测试过程中驱动10 mA/cm~2的电流密度分别需要147 mV和98 mV的过电势，表现出稳定的催化活性和循环稳定性。以CoFe/Ni(OH)_2/NF催化电极为阴阳极的全解水池在1.6 V工作电压下即可产生20 mA/cm~2的水分解电流密度，并具有100 h的耐久性，表现出高效的碱性全解水性能。
