22. The oxidation of benzenemethanol to benzoic acid on a reference graphite felt (non-oxidized) was very low. But the reaction was improved on an oxidized electrode, probably due to the formation of oxides at the surface of the fibres. See, for example: D. C. Alsmeyer and R. L. McCreery, Anal. Chem., 1992, 64, 1528; P. Chen and R. L. McCreery, Anal. Chem., 1996, 68, 3958; F. Regisser, M.-A. Lavoie, G. Y. Champagne and D. Bélanger, J. Electroanal. Chem., 1996, 415, 47. Thus, the oxidation of water was observed at more anodic potential using a reference felt compared to an oxidized one and the difference of reactivity between the two felts could be explained by the oxidation of alcohols by water oxidation intermediates..
