✦ Synopsis

The electrocatalytic oxidation of 1,2-propanediol has been investigated in acid medium both on bare Pt electrddes, and on adatom modified Pt electrodes. Relatively small enhancement catalytic effects are found with Cd, Pb and Re adatoms, whereas strong inhibiting effects are observed with Bi and Tl adatoms. An interpretation of the different behaviour of these adatoms is proposed on the basis of their potential range of redissolution, compared to the potential range of 1,2-propancdiol electrooxidation.
