    Abstract

    Pd-based multicomponent nanoporous metals were fabricated by electrochemically dealloying Pd20Ni60P20 metallic glass in an acid solution. The compositions and the pore size of the nanoporous metals were controlled by tuning the dealloying overpotential. The Pd-based nanoporous metal dealloyed at the critical potential presents superior electrocatalytic performances in formic acid electro-oxidation in comparison with the commercial Pd/C catalyst.
