Adsorption of l-lysine on a Cu(110) surface has been carried out under UHV condition from sublimation of a crystalline phase. The adsorption was characterised by FT-RAIRS, LEED and STM. At room temperature, the adsorption geometry of the lysine molecules varies as a function of the exposure. The low coverage phase sees the molecules adsorbed via the oxygen atoms of the deprotonated carboxylate group...
Nickel surfaces modified by optically active tartaric acid have been shown to be very effective in heterogeneous enantioselective hydrogenation reactions, but the performance of the catalysts is critically determined by the preparation conditions. Crucially, the enantioselective performance is linked directly to the presence of the chiral modifiers, yet little is known about the nature of the chiral...
