✦ Synopsis

AbetrsetLA study was carried out on the oxidation reaction of allylalcohol molecules on an

Au electrode in alkali medium. The kinetic study gives rise to three different reaction. mechanisms taking place at different potential ranges and under different experimental conditions. All the mechanisms studied are characterized by the interaction of the ally1 alcohol molecules with the Au-OH coverage, which produces radicals adsorbed on the surface and influencing, in this way, the reaction pathway. Under the conditions spe&cd in the text, a polymerization reaction appears to take place on the gold surface, which an -unt for the rather h,igh Tafel slope values obtained (b = 280 mV). The different mechanisms are discussed and compared with results obtained for Pt and gol&platin alloys[9].
