Abstract
The oxidation of methanol and C1 molecules was investigated on platinu m-modified polyaniline electrodes. It was found that such electrodes a re conducting even at 0.0 V vs RHE. They were found to have a higher e lectrocatalytic activity than bulk platinum electrodes. Moreover, the poisoning effect is drastically decreased as proved by in situ EMIRS s tudies which show no significant CO(ads) signal. Finally, kinetic resu lts show that the methanol electrooxidation is first order with respec t to methanol and that the main oxidation product is formaldehyde.
