Abstract

Cobalt oxyhydroxide and copper are electrodeposited on a dual-ITO substrate to obtain CoO_x(OH)_y/ITO and Cu/ITO, and cyclic voltammetry technique is applied for investigating the oxidation and reduction of pyruvic acid over CoO_x(OH)_y/ITO and Cu/ITO. The results reveal that pyruvic acid arises an oxidation current on CoO_x(OH)_y/ITO and a reduction current on Cu/ITO. Based on the results, potentials of 0.45V and -1.4 V are respectively applied on CoO_x(OH)_y/ITO and Cu/ITO by using chronoamperometry technique via dual-current channel. As a result, CoO_x(OH)_y/ITO has a linear response to pyruvic acid at relative low concentrations while Cu/ITO has a linear response at relative high concentrations, therefore the pyruvic acid detection in a wide concentration range (1.67 μmol·L^-1-6.01 mmol·L^-1) can be accomplished by the dual-electrode of CoO_x(OH)_y/ITO and Cu/ITO.
