Biomass-derivable materials investigated electrochemically included glucose, glucose derivatives, and lignosulfonic acid, with emphasis placed on glucose. Glucose was surveyed for evidence of electro-oxidation by cyclic voltammetry on shiny platinum, platinized platinum, rhodium, lead, and vitreous carbon. The electrochemical oxidation of glucose on the metal oxide anode materials, ruthenized titanium and lead ruthenate, was surveyed by recording steady-state current-potential curves because cyclic voltammograms recorded with these anode materials exhibited large residual currents. Each anode material was investigated for glucose electro-oxidative activity in electrolytes covering a pH range of 0.3 to 14.8. Electrochemical oxidation of the prototype carbohydrate, glucose, occurred at potentials more negative than oxygen evolution over a wide variety of experimental conditions. In general, glucose electro-oxidation was initiated most easily in alkaline electrolyte with all anode materials exhibiting some electro-oxidation in this electrolyte. Neutral electrolytes yielded the least electrochemical activity for glucose oxidation.
