  • Trends in Hydrogen Evolution Activity of MetalModified

    Abstract. Relatively high surface area nanocrystalline molybdenum carbide (Mo 2 C) was modified with 5 wt % silver, copper, nickel, platinum, and palladium nanoparticles and subsequently assessed for its hydrogen evolution reaction (HER) activity in alkaline and acid electrolytes. Density functional theory (DFT) calculated hydrogen binding energies predicted that PtMo 2 C and PdMo 2 C
