Nikolov, K. Petrov, T. Vitanov] The low temperature electrochemical oxidation of sulfur dioxide on carbon gas diffusion electrodes modified with cobalt phthalocyanine (CoPc) was studied. It was found that when operating with mixtures of air containing up to 20% by volume SO2 a basic problem of the electrooxidation of SO2, namely its permeation into the electrolyte, can be resolved. It is demonstrated that sulfur dioxide can be oxidized in the presence of air on active carbon, modified with cobalt phthalocyanine without external current at room temperature. The electrocatalytic character of the process is established and the rate dependence on the concentrations of H2SO4 and SO2 up to 0.30 vol % in air is displayed. An original method for the ‘cold oxidation' of SO2 to sulfuric acid is proposed. Chapman & Hall, 1996 Nikolov I. Central Laboratory of Electrochemical Power Sources, Bulgarian Academy of Sciences, G.
