In a proof-of-concept beamtime award (RB1220486) we studied the process of platinum-catalysed benzene hydrogenation in the pores of MCM-41 using standard neutron diffraction techniques on NIMROD. Our results have shown that following such reactions in a time-resolved manner is feasible (at suitable temperature and pressure conditions), and initial data indicates a clear two-step hydrogenation process. A full analysis of this data is underway. We intend to continue to probe the capabilities of the method by studying toluene hydrogenation in situ within the same catalyst. This system offers a different set of challenges, since the product distribution potentially consists of a number of isomers (while the benzene reaction did not). Again, we will complement the neutron scattering results with parallel NMR studies of the reaction.
