Vibrational spectroscopy has been used to probe the surface chemistry of two heterogeneous catalysts. This has principally involved the application of infrared (IR) spectroscopy and inelastic neutron scattering (INS), with a much reduced role for Raman scattering. Firstly, the activation of high surface area alumina catalysts has been investigated. IR spectroscopy is able to discern the presence of a recently postulated active site. Moreover, INS measurements indicate the potential of this technique to provide additional insight into the surface Lewis acidity of this substrate. The second part of this project uses the reaction of carbon monoxide and hydrogen over an Fe-based catalysts to discern some of the fundamental processes that are likely to contribute to the more complex Fischer-Tropsch synthesis (FTS) process. Ancillary measurements on an industrial grade FTS catalyst validate the procedure adopted.
