The voltammetric electrooxidation of glucose and glucose residues formed on electrodispersed platinum electrodes in acid electrolytes

The voltammetric electrooxidation of glucose and glucose residues on electrodispersed platinum electrodes in 0.5 M H2S04 solutions was studied at 2 C. The reaction produces weakly and strongly bound electroadsorbed residues whose formation depends on the adsorption potential, and the electrode surfa...

description The voltammetric electrooxidation of glucose and glucose residues on electrodispersed platinum electrodes in 0.5 M H2S04 solutions was studied at 2 C. The reaction produces weakly and strongly bound electroadsorbed residues whose formation depends on the adsorption potential, and the electrode surface characteristics. Weakly bound adsorbates are mainly formed on electrodispersed electrodes at potentials higher than 0.1 V (WE); strongly bound residues can be removed by setting the electrode in the HER potential range. The presence of molecular oxygen in the electrolyte changes the distribution of adsorbates. The amount of adsorbed residues formed on electrodispersed electrodes is a linear function of the electrode roughness factor. The behaviour of electrodispersed platinum electrodes for glucose electrooxidation can be interpreted in terms of particle size and preferential crystalline orientation effects on the reaction.
