Electrocatalysis of poly(2,3-diaminonaphthalene)-filmed electrodes for reduction of oxygen
Abstract
Poly(2,3-diaminonaphthalene)(PDAN)-filmed glassy carbon electrode, which can be prepared in situ by electropolymerization of the corresponding monomer, shows excellent electrocatalytic activity for O2 reduction to H2O2 in an acidic aqueous solution (pH 1.0), with an activation overpotential which is ca. 300 mV lower than that of the bare electrode.
