Accelerating hydrogen evolution at neutral pH by destabilization of water with a conducting oxophilic metal oxide

Self-supporting Ni₄Mo–V₂O₃ nanosheets, which combine oxophilic V₂O₃ as a water dissociation center with Ni₄Mo as a proton recombination site, display an extremely low overpotential (39.3 mV at 10 mA cm⁻²) for hydrogen evolution at neutral pH.
