英文摘要	Transition-metal nitrides have attracted a great deal of interest as electiocatalysts for water splitting due to their super metallic performance, high efficiency, and good stability. Herein, we report a novel design of hierarchical electrocatalyst based on Ni3FeN, where the presence of carbon fiber cloth as a scaffold can effectively alleviate the aggregation of Ni3FeN nanostructure and form three-dimensional conducting networks to enlarge the surface area and simultaneously enhance the charge transfer. The composition and morphological variations of NiFe precursors during annealing in different atmospheres were investigated. Such Ni3FeN/CC hierarchical electrocatalyst shows much improved electrochemical properties for water splitting in terms of over-potentials (105 and 190 mV at 10 mA/cm(2) for hydrogen evolution reaction and oxygen evolution reaction, respectively) and stability.
