Project Description

This PhD project forms part of a larger research project in collaboration with Professor Mark Keane (Chemical Engineering, Heriot Watt University). Gold can be used as a highly selective catalyst for hydrogenation reactions, but typically the rate of hydrogenation is slow due to the difficulty in dissociating the H-H bond over Au. This project aims to supply atomic hydrogen to supported Au nanoparticles via the dehydrogenation of an alcohol feedstock (e.g. butanol) in order to selectively hydrogenate aldehydes (e.g. furfural). Initial findings are that the supply of atomic hydrogen via coupled reactions leads to a large increase in the rate of aldehyde hydrogenation. In addition, this methodology removes the requirement to use high pressures of H2 to carry out the hydrogenation reaction. The role of the PhD student will be to fabricate and characterise Cu/Au bimetallic surfaces; to investigate the reaction mechanism over Cu/Au bimetallic model catalysts and to examine the effect of changing the oxide support on catalyst performance. The student will be trained in a number of characterisation techniques including scanning tunnelling microscopy (STM), reflection absorption infrared spectroscopy (RAIRS), temperature programmed desorption (TPD) and medium energy ion scattering (MEIS).
