Abstract :In the presem study the electrocatalytic effect of foreign metal monolayers deposited on platinized platinum electrode on the oxidation meclıanism of propanol was investigated. The explanation of the results were made by the comparision of current-potential curves obtained in the absence and presence of up to monolayers of Gd, Tl, Bi, Hg and Au on Ptz-Pt electrode. It was found that Au, Cd and Au monolayers have good catalytic effects, But Bi, Hg, Tl inhibit the oxidation of propanol. At the same time, experiments confirrn the previously postulated mechanism of propanol oxidation. The absorption energy or bond strenth of Pt-H or Pt-Me is an important factor that determine the oxidation rate of propanol.
Keywords : In the presem study, metal monolayers deposited, At the same time
