Surface catalysis studied by in situ positron emission

Positron emission imaging in catalysis

“…The university's 30 MeV AVF cyclotron is used to prepare the positronemitting nuclides: l tc; 13N and 150. Building on the initial successes of Jonkers et al [28,29] the aim of this project is to extend the scope of this technique to catalytic reactions involving molecules more complex than the diatomic and triatomic molecules made previously.…”

“…The first application of PET to the study of chemical reactions was conducted by Jonkers and coworkers [28,29]. These pilot experiments were performed at the State University of Gent, Belgium, using a commercial PET-camera designed for medical imaging, the NeuroECAT tomograph described above.…”

Positron Emission Profiling: a Study of Hydrocarbon Diffusivity in MFI Zeolites

“…Jonkers and co-workers conducted the first study in which PET was applied to chemical reactions in reactors [32,33]. Since the early 1990s a facility has been developed at the Eindhoven University of Technology (TU/e) dedicated to positron emission imaging of physical and chemical processes in catalytic reactors at practical operating conditions.…”

Production of 11C-labelled n-hexane for use in positron emission imaging

In the field of catalysis therefore positron emission tomography would allow one to study labelled reactants inside a working catalyst bed; with conventional techniques of analysis it is only possible to study those reactants entering the catalytic reactor, and the products leaving.…”

“…In the field of catalysis therefore positron emission tomography would allow one to study labelled reactants inside a working catalyst bed; with conventional techniques of analysis it is only possible to study those reactants entering the catalytic reactor, and the products leaving. The technique was used fairly recently to study CO oxidation over automotive catalysts [5,6].…”
