چکیده:

Electrocatalytic processes involving the oxidation of sugars are of great interest in many areas, ranging from medical applications to wastewater treatment, from the construction of biological fuel cells to analytical applications in the food industry [1–۳]. On the other hand, the electrochemical detection of carbohydrates is important in many areas [4].
The electrochemistry of carbohydrates on various electrode materials, e.g. Au, Pt, Ni, Cu and glassy carbon continues to be of interest as these materials could find use for a fuel [5]. The purpose of the present work is to study the electrochemical oxidation of saccharose on a nickel electrode in a solution of 1 M NaOH. The electro-oxidation of saccharose on nickel in alkaline solutions has been studied by the method of cyclic voltammetry. It has been found that in the course of an anodic potential sweep the electro-oxidation of saccharose follows the formation of Ni (III) and is catalyzed by this species through a mediated electron transfer mechanism.
