摘要：
The SO2 adsortion in (100) and (111) preferentially orientated platinum surface was studied. The results were compared to those obtained with polycrystalline polished platinum. The potentiodynamic electrodesorption charge for different adsorption times with constant SO2 concentration was determined. The plot exhibited a series of plateau which were attributed to successive SO2 layer formation. A reaction ocurrs over the first layer, with sulphur formation. The ocurrence of this reaction is favoured on Pt with (100) preferential orientation.
