Abstract
The Pd-Ni alloy nanoparticles with nickel atomic contents of 12.0%, 16.4% and 22.6% were successfully electrodeposited from a Pd-Ni alloy electrolyte by square wave pulse plating. The alloy nanoparticles were in the spherical shape with a diameter of 50 ~ 80 nm. As the growth potential of the alloy was negatively shifted, the nickel content of the alloy was increased, and the size of the nanoparticles was almost the same, whereas the number, the degree of crosslinking and the real active area of the nanoparticles were increased. As the nickel content of the alloy nanoparticles increased, the peak current for weakly adsorbing hydrogen was increased. The alloy nanoparticles electrodes were shown in a good electrocatalytic oxidation activity to formic acid. The electrocatalytic oxidation stability of the alloy nanoparticles was increased by the increases of the number and the degree of crosslinking.
