Selective Production of Reactive and Nonreactive Oxygen Atoms on Pd(OOl) by Rotationally Aligned Oxygen Molecules

摘要

The improvement of product yields is one of the most important goals for surface science, which is a discipline that aims at a thorough understanding of heterogeneous catalysis and the future design of knowledge-based catalysts.Simple reactions, such as dissociative O2 adsorptionand CO oxidation,feature among the most frequently studied processes because of their paradigmatic role and apparent simplicity. The elementary steps of simple chemical reactions can be studied by performing state-resolved experiments with supersonic molecular beams (SMBs). As recently demonstrated, this technique also allows the exploration of the influence of the rotational alignment of the reactants by performing an accurate velocity selection of the molecules that are seeded in lighter inert carriers.
