The combined use of spectroscopic and reaction tools to investigate mechanistic aspects of heterogeneous catalysis
The group are involved in understanding the nature of solid surfaces, mainly catalytically active surfaces and in relating knowledge gained through examination of these surfaces with how they perform in catalytic reactions. The reaction of choice are usually those which involve activation of hydrocarbons although we are also interested in NO and CO oxidation and other reactions related to vehicle emission catalysts and to CO hydrogenation for Fischer Tropsch reaction for the manufacture of synthetic fuels. Our approach involves the combined use of spectroscopic and reaction tools to investigate mechanistic aspects of heterogeneous catalysis. We have reactors which permit vibrational spectra to be obtained under conditions of high pressure and temperature and coupling these with analytical instrumentation for assessment of products and reagent conversion proves to be a useful tool in assessing surfaces in reaction. In particular, we are keen to use vibrational spectroscopy in a quantitative manner which then allows quantification of surface species/surface sites to be established. We employ such methodology for solid oxides (and mixed oxides) and supported metals and bimetallics. Understanding of these reactions and the number of participating sites allows us to design and develop modifiers which then permit enhanced selectivity to be attained.
The successful applicant should have, or expect to have, an Honours Degree at 2.1 or above (or equivalent) in chemistry or chemical engineering or MSc in materials or catalysis related subject with knowledge in Surfaces, spectroscopy, materials.
