•Hierarchical VN nanostructures were prepared on graphite foam.•Electrolyte preference of VN supercapacitor electrodes was explored.•VN showed better capacitive property in organic and alkaline electrolytes than LiCl.
Vanadium nitride hierarchical nanostructures were prepared through an ammonia annealing procedure utilizing vanadium pentoxide nanostructures grown on graphite foam. The electrochemical properties of hierarchical vanadium nitride was tested in aqueous and organic electrolytes. As a result, the vanadium nitride showed better capacitive energy storage property in organic and alkaline electrolytes. This work provides insight into the charge storage process of vanadium nitride and our findings can shed light on other transition metal nitride-based electrochemical energy storage systems.
