Selective oxidation of carbohydrates on Nafion (R)-TEMPO-modified graphite felt electrodes

The TEMPO-mediated oxidation of carbohydrates was investigated iu heterogeneous conditions. The aminoxyl radicals were immobilised in a Nafion(R) film on graphite felt electrodes. This selectively gave rise to the corresponding uronic acids. Analytical results targeted towards the kinetics and the stability of the electrodes are also reported. (C) 2001 Elsevier Science B.V.
