摘要
Abstract Replacing the slow oxygen evolution reaction (OER) with favorable hydrazine oxidation reaction (HzOR) is a green and efficient way to produce hydrogen. In this work, we synthesize amorphous/crystalline RhFeP metallene via phase engineering and heteroatom doping. RhFeP metallene has good catalytic activity and stability for HER and HzOR, and only an ultralow voltage of 18 mV is required to achieve 10 mA cm-2 in a two-electrode hydrazine-assisted water splitting system. The superior result is mainly ascribed to the co-doping of Fe and P and the formation of amorphous/crystalline RhFeP metallene with abundant phase boundaries, thereby adjusting electronic structure and increasing active sites.
