Abstract

The coulombic efficiencies of Pd-Au/C catalysts for the electrochemical oxidation of borohydrides were measured and the impregnated states of Pd-Au were characterized by XRD and XPS to find their relevance to the catalytic performances of the catalysts. The Pd-Au/C (metal wt.% = 20%) catalysts showed coulombic efficiencies of 50-70% under the given galvanostatic conditions, with maintaining a current density close to 20% Pd/C at voltammetric test, which is thought to be related to the mixed state of monometallic Au and Pd-Au alloy on the carbon support.
