摘要：

Nickel modified graphite electrodes(G/Ni) prepared by galvanostatic deposition were examined for their redox process and electrocatalytic activities towards the oxidation of methanol,ethanol,1-propanol and 2-propanol in alkaline solutions.The methods of cyclic voltammetry(CV),chronoamperometry(CA) and impedance spectroscopy(EIS) were employed.In CV studies,the electrochemical response,peak current varied in the order of MeOH > EtOH > 1-PrOH > 2-PrOH.Under the CA regime,a higher catalytic rate constant obtained for methanol oxidation was in agreement with CV measurements.Lower charge transfer resistance was obtained for low carbon alcohols oxidation and significantly higher exchange current density was obtained for methanol oxidation.
