摘要
To improve the electrochemical performance of Pd-based catalysts for formic acid oxidation, a carbon supported nanoporous PdNi catalyst is prepared by dealloying high-Ni-content PdNi alloy nanoparticles in acid solution. The structure of nanoporous PdNi/C catalyst is characterized by X-ray diffraction, transmission electron microscopy and X-ray photoelectron spectroscopy. The electrocatalytic results show that the activity of the nanoporous PdNi/C catalyst is higher than that of nonporous Pd/C catalyst. The results demonstrate that the carbon-supported nanoporous PdNi catalyst has a potential for application in direct formic acid fuel cells.
