Abstract
The study of electrochemical behaviour of dispersed Ni on graphite, glassy carbon, and Ti electrodes, obtained by an electro-deposition method, is carried out in 1 M KOH + 1 M CH3OH at 25 °C. Results show that the nature of substrate influences the apparent electrocatalytic activities of the Ni over layer greatly. It is observed that at E = 0.50 V vs. Hg/HgO (25 °C), the dispersed Ni on graphite is approx. 300 times more active than that dispersed on Ti and is approx. 260 times more active than that dispersed on glassy carbon. Further, these electrodes show quite good resistance against electrode poisoning by the methanol oxidation intermediates/products.
