Title The Effect of Oxygen Adsorption on the chiral Pt{531} Surface
Abstract Single enantiomers of bio-relevant chiral molecules are essential in the production of most drugs; new technologies for enantioselective catalysis could therefore have a major impact on the design and production process of modern drugs. The further development of heterogeneous methods by introducing enantioselective catalyst surface geometries would, to this end, harness the distinct advantages of heterogeneous processes over the homogeneous methods predominantly in use. One of the principal strategies for enantioselective heterogeneous catalysis is to use a chiral substrate to ‘stereodirect’ a surface reaction. Certain high Miller-index stepped-kinked surfaces of symmetric bulk crystal structures are intrinsically chiral because they have no mirror planes. There are some examples in the literature of enantioselective reactions on such surfaces of Pt and Cu. However, it is rather difficult to discriminate between enantiomers with most conventional Surface Science techniques because they probe only scalar quantities (e.g. mass, vibrational frequency, electronic binding energy). Only crystallographic methods and polarisation-dependent optical methods are able to discriminate directly between enantiomers.
