Abstract

We report the formation of Pd-based multicomponent nanoporous metals by electrochemically dealloying the Pd_80-xNi_xP₂₀ 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 Pd_80-xNi_xP₂₀ 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.
