Modulating electronic structure of self-supported nickel-vanadium layered double hydroxide to accelerate hydrogen evolution reaction

The development of efficient and cost-effective electrocatalysts for hydrogen evolution reaction (HER) is an urgent requirement but formidable challenge. In this work, Co and Mn were introduced into self-supported nickel-vanadium layered double hydroxide (NiV?LDH) to modulate electronic structure. T...
