Nickel-modified glassy carbon electrode (GC/Ni) prepared by galvanostatic deposition was used for the electrocatalytic oxidation of glucose in alkaline solutions where different electrochemical methods were employed. In cyclic voltammetry studies, in the presence of glucose an increase in the peak current of the oxidation of nickel hydroxide is followed by a decrease in the corresponding cathodic current. This suggests that the oxidation of glucose is being catalyzed through mediated electron transfer across the nickel hydroxide layer comprising nickel ions of various valence states. Under the chronoamperometric regime, the reaction followed a Cottrellian behavior and the diffusion coefficient of glucose was found to be 8 × 10 −6 cm 2 s −1 . A mechanism based on the electrochemical generation of Ni 3+ -active sites and their subsequent consumptions by glucose has been discussed, and kinetic parameters have been derived. The heterogeneous rate constants for the oxidation of glucose at the surface of modified electrodes were determined by rotating disk electrode using the Koutecky-Levich plots, which are in agreement with the data obtained by chronoamperometry.

“…Many studies have been devoted to the investigation of the electrochemical behaviour of nickel electrodes in alkaline solutions in order to understand the processes undergoing on the electrode surface and to examine the possibility of their exploitation for analytical purposes [16,17,[21][22][23]. The anodic oxidation of nickel based electrodes in alkaline media produces the thin film of metal hydroxide and oxihydroxide acting as a catalyst in electron transfer and enhancing the electrode processes [24][25][26]. Due to the effective electrocatalytic action of the redox Ni(OH) 2 /NiOOH couple, many organic compounds can be electro-oxidised at moderate potentials on nickel based electrodes [17,27,28].…”

The electrocatalysed oxidation of histamine on a thin film nickel electrode was investigated for the purpose of its chronopotentiometric determination. The oxidation mechanism implies complex and combined processes of histamine physical adsorption and consequent oxidation via joined oxidation potency of a constant current and electrochemically generated nickel-oxihydroxide, which played a role of an electron transfer catalyst. Experimental parameters affecting the oxidation process, including type and concentration of supporting electrolyte, initial potential, oxidation current, temperature and concentration time, were optimised. Using a 240 s accumulation time, limit of detection and quantitation were 0.11 mg L À1 and 0.29 mg L À1 of histamine, respectively.
