Electrocatalytic oxidation of methanol and C1 molecules on highly dispersed electrodes Part 1: Platinum in polyaniline

The oxidation of methanol and C1 molecules was investigated on platinum-modified polyaniline electrodes. It was found that such electrodes are conducting even at 0.0 V vs RHE. They were found to have a higher electrocatalytic activity than bulk platinum electrodes. Moreover, the poisoning effect is drastically decreased as proved by in situ EMIRS studies which show no significant CO_ads signal. Finally, kinetic results show that the methanol electrooxidation is first order with respect to methanol and that the main oxidation product is formaldehyde.
