Infrared spectroscopy has been employed to study the chemisorption of CO by Pd crystallites supported on SO2. At 80 K, it has been found that the adsorption of terminally bound CO species on Pd saturated with bridged-CO species results in the stoichiometric conversion of two CO-bridged species to terminal-CO species for each terminal CO adsorbed. The local character of this stoichiometric conversion process suggests that local donor-acceptor concepts operate at the sites experiencing the conversion. Comparisons of behavior on small Pd crystallites and on Pt( 1 11) are made, and it is found that remarkable similarities exist as well as differences.
