In this Communication, we report a high-efficiency electrocatalyst for electrochemical water oxidation based on an Fe-doped NiP nanosheet array on a conductive carbon cloth. This catalyst shows a low onset overpotential of 190 mV, and it demands overpotentials of only 215 and 235 mV to drive 50 and 100 mA cm, respectively, with high electrochemical durability. This work offers us an attractive earth-abundant 3D catalyst electrode in water-splitting devices toward the mass production of hydrogen fuels for applications.
在本通讯中，我们报道了一种基于导电碳布上的铁掺杂NiP纳米片阵列的用于电化学水氧化的高效电催化剂。该催化剂起始过电位低至190 mV，驱动电流密度分别达到50和100 mA cm²时所需的过电位仅为215和235 mV，且具有高电化学耐久性。这项工作为我们提供了一种极具吸引力的、储量丰富的三维催化剂电极，用于水分解装置中大规模生产氢燃料以供应用。
