In Situ Monitoring of Iron-Catalysed Reactions by High-Field NMR Spectroscopy


A reactor for in situ high-field gas-phase NMR techniques for the investigation of heterogeneous hydrogenation reactions on supported iron nanoparticles and small iron clusters is developed. The reactor is employed to study the catalytic H/D-isotope scrambling of H2/D2 mixtures, the para-/ortho-H2 conversion of parahydrogen (pH2) by the catalyst and the hydrogenation of unsaturated carbon-carbon bonds of propyne and ethyne to propene or ethene. The potential of the catalysts to generate hyperpolarized propene and ethene by ParaHydrogen Induced Polarization (PHIP) for NMR and MRI applications is evaluated.
