Abstract
Catalytic activities and the lifetime of chemically modified glassy carbon electrode by polystyrene(PS) and cobalt phthalocyanine(CoPC) were investigated in the reduction of oxygen by the measurements of current-potential curves in 6N KOH aqueous solutions. The PS coated electrode behaved in the same manner as the glassy carbon electrode without treatment (GCE), without any obvious current decrease and potential shift of the wave. The electrode coated with the PS containing the CoPC showed higher catalytic activities than the GCE during a long continuous operation, which had a longer life than the electrodes on which the CoPC was directly attached by the adsorption or the chemical modification.Keywords
