• Pd-based nanoporous metals were prepared by dealloying Pd80−xNixP20 glasses.
• The composition and pore size of the nanoporous metals are tunable.
• The Pd-based nanoporous metals show superior catalytic activity.
We report the formation of Pd-based multicomponent nanoporous metals by electrochemically dealloying the Pd80−xNixP20 metallic glasses. It was found that both the compositions and the pore sizes of the nanoporous metals can be tailored by the Ni content in the glassy Pd80−xNixP20 precursors. Moreover, the Pd-based nanoporous metal with the optimized composition and the pore size exhibits better electrocatalytic performance towards the oxidation of the formic acid when compared with the commercial Pd/C catalyst.
