We are reporting the electrochemical behavior of bimetallic Sn-Pd catalysts in ethanol oxidation reaction (EOR). Sn-Pd catalysts were prepared by two step electrodeposition technique whereby by regulating deposition conditions various forms of Sn dendrites and different atomic ratios of Sn:Pd were achieved. The electrocatalytic activity of Sn-Pd catalysts were evaluated for EOR in alkaline solution using cyclic voltammetry (CV) and chronoamperometric (CA) measurements. The highest activity and anti-poisoning ability exhibited Sn0.67-Pd0.33 catalyst due to the better utilization of Pd. At Sn0.67-Pd0.33 catalyst Sn better contribute Pd to oxidize chemisorbed species by providing adsorbed OH- species, thereby enabling well synergy of Sn with Pd
U ovom radu se bavimo ispitivanjem elektrohemijskog ponašanja Sn-Pd katalizatora u reakciji oksidacije etanola (ROE). Sn-Pd katalizatori su dobijeni dvostepenim elektrohemijskim taloženjem, pri čemu se regulisanjem uslova taloženja dobijaju različite forme Sn dendrita i različiti atomski odnosi Sn:Pd. Elektrohemijska aktivnost Sn-Pd katalizatora je procenjena u ROE u alkalnoj sredini korišćenjem ciklične voltametrije (CV) i hronoamperometrijskim merenjima. Najveću aktivnost i toleranciju prema otrovima je pokazao Sn0.67-Pd0.33 katalizator zbog boljeg iskorišćenja Pd. Primećeno je da kod Sn0.67-Pd0.33 katalizatora Sn bolje doprinosi oksidaciji hemisorbovanih čestica na Pd obezbeđivanjem OH- čestica, omogućujući tako dobru sinergiju Sn sa Pd.
