Article abstract of DOI:10.1139/v94-289

The electrocatalytic activity of nickel boride in the electrocatalytic hydrogenation of phenanthrene in ethylene glycol-water at 80°C has been compared to that of Raney nickel and fractal nickel. It is shown that the intrinsic activity of the electrode material (real electrode activity) is the same for nickel boride and Raney nickel electrodes and is lower for fractal nickel electrodes. The apparent electrode activity of nickel boride pressed powder electrodes is less than that of codeposited Raney nickel electrodes and pressed powder fractal nickel/Raney nickel electrodes. The relation in terms of the Tafel and alternating current impedance parameters are also determined.
