Interest in the surface chemistry of late transition-metal oxides has been stimulated by observations that the formation of metal oxide layers tends to dramatically alter the catalytic performance of transition metals in applications of oxidation catalysis. In this talk, I will discuss our investigations of the surface chemical properties of a PdO(101) thin film, focusing on the adsorption and activation of alkanes as well as the oxidation of CO. I will discuss characteristics of the binding and activation of alkane σ-complexes on PdO(101) as determined from both experiment and density functional theory calculations. I will also discuss elementary processes involved in the oxidation of CO on PdO(101) and the role that surface oxygen vacancies play in mediating reaction.
