摘要：

Earth-abundant, low-cost, and highly active bifunctional electrocatalysts are of significant importance to the large-scale production of hydrogen from water electrolysis. Herein, it is reported that novel FeNi3/NiFeOx nanohybrids display high electrocatalytic activities in both hydrogen evolution reaction (HER) and oxygen evolution reaction (OER). These FeNi3/NiFeOx nanohybrids are obtained with the unique hydrogenation treatment of NiFeOx nanosheets. Small onset potentials of approximate to 20 and 240 mV are obtained for HER and OER, respectively, benefited from the synergistic effect of FeNi3 and NiFeOx. Only a small voltage of 1.55 V is needed to reach a current density of 10 mA cm(-2) for the overall water splitting in an alkaline electrolyzer when using FeNi3/NiFeOx as both cathode and anode catalysts. This is one of the best performance of electrocatalysts for HER and OER, shining the bright future for earth-abundant, low-cost bifunctional electrocatalysts for largescale production of hydrogen from water electrolysis.
