This paper presents potentialities of time-of-flight secondary ion mass spectrometry in surface characterization of palladium catalysts destined for hydrodechlorination reaction. The secondary ion mass spectra collected from the surface of the analyzed catalysts allowed to obtain useful information regarding surface composition, presence of contaminants and interactions between particular surface components. Moreover, the amount of Cl containing species formed on the catalyst surface during hydrodechlorination reaction was also estimated.
