The deactivation of metals by some specific impurity is a serious industrial problem. The use of Surface Science techniques has recently provided new insights into the mechanisms of poisoning. Advantages and limitations of such an approach have been recently discussed. As a result of its strong interaction with metals, sulfur is one of the most detrimental elements. On most transition metals, it can be active at a very low level in the gas phase especially in hydrogenation conditions. In this paper, the authors intend first to summarize some of the main features of the effect of sulfur on molecular adsorption, then focus on recent results on the effect of sulfur on the hydrogen adsorption from acid solution and on the butadiene hydrogenation on platinum single crystals.
