Summary on Grant Application Form
The major objective of this work is to investigate how sustained changes in catalyst selectivity can be induced by small doses of surface modifiers which would normally be regarded as catalyst poisons. Of prime initial importance are oxide-supported metal catalysts for the hydrogenation of molecules containing at least two sites for potential hydrogenation. Optimising selectivity in favour of commercially desirable products is a key aim and will be explored for particular reactions by varying catalyst composition, the nature of the modifiers and experimental conditions during both surface modification and catalysis. Detailed catalystic studies will be linked to characterisation using spectroscopic methods (FTIR, Raman, XPS, MASNMR, STM) in order to gain a fundamental understanding of the modes of adsorption of and the changes in catalyst surface character induced by the modifiers, and also to assess how the modifiers influence the adsorptive, desorptive and reactive characteristics of reactants, intermediates and products in the catalytic reactions. Overall, it is intended that a fundamental understanding of these systems will lead to the development of novel catalysts giving high selectivity to desirable products. The research programme will initially study the hydrogenation of stable unsaturated compounds using Cu/A1203 with stable S containing modifiers.
