Abstract：
The electrochemical deposition behavior of Pd-Ni bimetal on glassy carbon (GC) electrode was studied by means of cyclic voltammetry (CV) based on orthogonal experiments. The optimum preparation conditions of Pd-Ni/GC electrode were Ni2+=8.5 mmol·L-1, Pd2+=3 mmol·L-1, pH=7.0, Jk=15 mA·cm-2, and T=30 min. The hydrogen adsorption peak on Pd-Ni/GC electrode of -24.83 mA was obtained at about -500 mV (vs Hg/Hg2SO4). Pd-Ni/PPy/GC electrode modified by polypyrrole film was prepared. CV results revealed that the hydrogen adsorption peak of -32.33 mA was obtained at about -500 mV (vs Hg/Hg2SO4), which was larger than that on Pd-Ni/GC electrode. Scanning electron microscope (SEM) images revealed that PPy film changed the deposition configuration of Pd-Ni particles evidently. The diameters of Pd-Ni microparticles were smaller and the dispersion degree was higher.
