Summary on Grant Application Form |
The project will be based on very recent experimental and theoretical findings in our laboratory that all kinked single crystal surfaces are chiral due to the inherent left- or right- handedness of the kink sites. The effect is demonstrated for Pt {643}-S and Pt {643}-R electrodes in relation to the electro-oxidation of D- and L- glucose. Consequently, a series of experiments based on a rigorous surface science approach may be proposed whereby the various mechanisms of enantioselectivity in the model hydrogenation system ethyl pyruvate/cinchonidine/Pt/hydrogen may be tested. A new mechanism for this reaction is also proposed in which the strong selective adsorption of either cinchonidine or a cinchonidine/ethyl pyruvate complex at kink sites of a particular chirality results in vacant chiral platinum kink sites (of opposite chirality) for the selective hydrogenation of ethyl pyruvate. A combination of LEED-AES, cyclic voltammetry, STM, chiral single crystal , manufacture, in situ surface IR and a novel wall-jet apparatus capable of examining charge transients generated at the chiral electrode under well-defined electrolyte flow will be used to examine this phenomenon.
