摘要：

The electrocatalytic oxidation of small organic molecules (methanol, ethylene-glycol, glyoxal, propane-diols and glucose) at electrodes modified or unmodified by lead adatoms was investigated in order to follow the formation and to determine the concentration of the different products involved. Prolonged electrolyses of the organic compounds were carried out at controlled-programmed potentials with different potential programmes including cleaning sequences of the working electrode. Analyses of products were performed with "on-line" gas and liquid chromatographies. The kinetics of the overall reaction can be determined from these results and the different factors which modify the electroactivity of the electrode and the selectivity of the reaction are discussed.
