摘要：

The influence of the electrolyte composition on the kinetics and mechanism of glucose electro-oxidation has been investigated on microcolumnar Au electrodes. Neutral electrolyte solutions containing either sulphate, phosphate, borate or perchlorate anions were employed. The results show that the glucose electro-oxidation reaction on this type of Au electrode is favoured in those electrolytes with a high buffer capacity and is inhibited by anion adsorption. The electro-oxidation process involves the formation of weakly and strongly bound adsorbates acting as poisons. Bulk glucose electro-oxidation apparently takes place without the formation of a detectable amount of adsorbed intermediates.
