Very rapid transient measurement of a methanol electrooxidation reaction on Pt and Pt-spe was carried out for the purpose of elucidating the reaction mechanism in acidic solution. After anodic activation treatment we observed a positive reaction current density of 1.2 mA cmm2 as a maximum value at a

β¦ Synopsis
The electrooxidation of benzyl alcohol was investigated employing a Pt-Nation composite electrode in both polar and non-polar solvents. The use of hexane as a solvent caused the current effciency for benzaldehyde formation to increase greatly compared with that in acetonitrile. Furthermore, the stability of the Pt-Nafion composite electrode for the repeated electrolyses was largely improved by the use of hexane.
