Herein, we codoped vanadium nitride (VN) nanowires with cobalt (Co) and phosphorus (P) via a simple hydrothermal and postannealing approach and used as hydrogen evolution reaction (HER) and oxygen evolution reaction (OER) electrocatalysts. Benefiting from the synergistic effect from excellent properties of individual Co, P, and VN, the as-prepared VN-Co-P electrocatalyst displays lower onset overpotentials (137 and 335 mV), lower Tafel slopes, and more excellent stability than VN and VN-Co during HER and OER and shows promising electrocatalysts for HER and OER in alkaline solutions.
