Active in alkaline environment: The activity of nickel, silver, and copper catalysts for the electrochemical transformation of water to molecular hydrogen in alkaline solutions was enhanced by modification of the metal surfaces by Ni(OH)2 (see picture; I=current density and η=overpotential). The hydrogen evolution reaction rate on a Ni electrode modified by Ni(OH)2 nanoclusters is about four times higher than on a bare Ni surface.
