摘要：

The amount of hydrogen evolved during the oxidation of formaldehyde at Ib electrodes was determined as a function of the potential. The current efficiency (amount of H-2 per two anodic electrons) can exceed 100% suggesting a reaction sequence which involves the (non-electrochemical) dissociation of a formaldehyde molecule into H-2 and HCOO-. Further suppport for such a potential dependent and heterogeneously catalyzed chemical reaction is given by isotope experiments. Smaller amounts of hydrogen are also evolved during the oxidation of acetaldehyde and propionaldehyde, showing that the release of a hydrogen molecule can also be coupled to electrochemical oxidation.
