A fcc nanoporous palladium (NP Pd) with a pore size of ∼2 nm and ligament size of ∼4 nm is obtained after electrochemical dealloying an amorphous Pd42.5Cu30Ni7.5P 20precursor in a 0.1 mol dm-3H2SO 4solution at constant current densities of 17 mA cm-2for 12 ks. A nanoporous Pd-P solid solution forms at lower currents. The cyclic voltammetry results reveal that NP Pd has a superior ethanol oxidation ability, about 20 times higher oxidation current than bulk Pd in the alkaline conditions. This can be attributed to the small pore sizes and fine ligaments of the NP Pd electro-catalysis.
