•The ECSA is increased through producing heterogeneous interfaces.•The electron state of Ni, Co is modulated by introducing V and generating interfaces.•The V-CNS/P/NF only requires an overpotential of 38 mV at 10 mA cm−2 for HER. Developing efficient and robust non-noble electrocatalysts for hydrog...
