What is it about?
This scientific publication investigates the reaction intermediates that form on the surface of a catalyst called Raney-Co during the hydrogenation of acetonitrile (CD3CN) using a technique called inelastic neutron scattering (INS). By analyzing the spectra of different potential reaction intermediates and comparing them with reference spectra of H2, CD3CN, and CD3CH2NH2, the researchers were able to obtain detailed information on the structure of the adsorbed molecules. They found that CD3CN reacted preferentially with hydrogen bound to specific sites on the Co-surface. On the surface, a mixture of a nitrene-like intermediate and co-adsorbed CD3CH2NH2 was formed, as indicated by a strong CH2 twisting vibrational mode. The study provides valuable information about the mechanism of the hydrogenation reaction and the behavior of the catalyst.
