Electrochemical oxidation of glucose on a platinum electrode at 523 K

Using a pressure cell equipped with an Ag|AgCl|0.1 M KCl external pressure-balanced reference electrode (EPBRE), glucose was potentiostatically electro-oxidized on a Pt electrode at 0.8 V vs. RHE at 523 K. The products and the decomposition efficiency of glucose were compared with those without electrolysis. It was estimated that the electrochemical oxidation of glucose at 523 K involves 2-13 electrons. However, it was difficult to control the decomposition efficiency of glucose with our experimental cell. The construction of a cell with short residence time may be required for the further quantitative study on the electrochemical oxidation of glucose at high temperature.
