Abstract:The status of surface species on solid catalysts during heterogeneous catalysis is often mysterious. Investigations of these surface species are crucial to deconvolute the reaction network and design more efficient catalysts. Vibrational spectroscopy is a powerful technique to study the interactions between surface species and the catalysts and infrared (IR) and Raman spectroscopies have been widely applied to study reaction mechanisms in heterogeneous catalysis. However, IR/Raman spectra are difficult to mode… Show more
“…2 Therefore, probing early reaction stages, including butane-Brønsted acid site interactions, would be of great interest in optimising alkane transformations within zeolites. Inelastic neutron scattering (INS) is well suited to probing interactions between inorganic catalysts and hydrocarbon substrates, 5,6 as the neutron scattering cross section of hydrogen is by far the largest of all elements. Thus, any hydrogen in a system will dominate the INS spectra, even when present in small quantities.…”
