The irreversibly adsorbed anthraquinone-2-carboxylic-allyl ester (abbreviated as ACAE) on a graphite electrode displays strong electrocatalytical activity for the two-electron reduction of oxygen to form hydrogen peroxide. The surface electrochemistry of ACAE was examined by cyclic voltammetry. A two-electron, two-proton electrochemical redox process of the quinone group in the ACAE molecule was identified. A rotating disk electrode method was used to obtain the kinetic parameters of the electrocatalyzed reduction of oxygen. The high selectivity of ACAE for the two-electron reduction of oxygen in pH<7 aqueous solution was demonstrated. The possible application of ACAE in H2O2 production is also explored in this paper. |
