Abstract

<span style="font-size:11.0pt;font-family: " times="" new="" roman";mso-fareast-font-family:"times="" roman";mso-bidi-font-family:="" mangal;mso-ansi-language:en-gb;mso-fareast-language:en-us;mso-bidi-language:="" hi"="" lang="EN-GB">Electrocatalytic activity of a new catalyst towards the oxidation reaction of hydroquinone as a model compound is described. The catalyst is formed by immobilizing Cu(II) ion on the top side of a gold-L-cysteine self assembled monolayer electrode. Preparation steps and the electrocatalytic activity of Au-L-cysteine-Cu²⁺ have been studied by cyclic voltammetry and electrochemical impedance spectroscopy. The Au-L-cysteine-Cu²⁺ electrode exhibits better electrocatalytic activity than Au-L-cysteine and bare Au electrode for the oxidation of hydroquinone.</span>
