Abstract

Electrochemical oxidation of hollow sporopollenin particles immobilised on an electrode surface is investigated in aqueous acidic solution. Redox activity is demonstrated to occur via a mixture of 2e--2H+ and 2e--1H+ processes, likely due to the oxidation of conjugated phenolics embedded within the surface-shell of the polymer particles. Charge transport over the surface is suggested to be fast based on comparison with an approximate physicochemical model.
