Enantioselective surface reactions represent the ultimate
expression of selectivity in catalysis, involving stereodirecting
processes where only one optical component of a product is formed.
At present, however, the technique of catalyst modification is
imperfect and the knowledge of the surface structure of the solid
insufficient. The purpose of this thesis is to provide an
understanding of the various phenomena occurring on solid
enantioselective catalyst surfaces. For this purpose, model
stereodirecting surfaces have been created by the adsorption of the
chiral modifier, (R, R)-tartaric acid, and (S, S)-TA, on a
well-defined Ni(110) single crystal surface. This chiral molecule
is well known for stereodirecting the enantioselective
hydrogenation of beta-keto-esters. RAIRS, TPD, LEED and STM data
presented in this thesis show that when tartaric acid molecules
adsorb on a Ni(110) surface, a complex adsorption phase diagram is
obtained, where the chemical identity and two-dimensional order of
the adsorbed species varies significantly as a function of coverage
and temperature. The Chirality is expressed by creating a chiral
footprint at the surface linked to the adsorbed molecule.
