Facile Synthesis of Copper-Coated-Reduced-Graphene-Oxide and Its Application as a Highly Sensitive Electrochemical Sensor for Hydroquinone

<div>(a) Storage stability of Cu/rGO/GCE stored in a constant temperature drying oven, (b) the selectivity of the proposed method for HQ determination. The concentration of HQ is 5 <i>μ</i>M, concentrations of phenol, resorcin, catechol, glucose, and benzoic acid are 0.5 mM, concentration of inorganic ions is 1 mM; the error bars illustrate the standard deviations of six independent measurements.</div>
