Characterisation of ethylene adsorption on model skeletal cobalt catalysts by inelastic and quasi-elastic neutron scattering

Neutron Scattering Studies of Heterogeneous Catalysis

“…218 Jones and co-workers have used the recently upgraded TOSCA spectrometer 219 to use ethene adsorption on model skeletal cobalt catalysts to characterize the active site distribution. 220 Reminiscent of the work of Kelley and coworkers examining adsorption on Raney nickel, the new cobalt studies revealed the presence of highly active sites that induced adsorbate dehydrogenation. In general agreement with a preceding study by Davidson and co-workers on cobalt-based prototype Fischer−Tropsch synthesis catalysts, 119 as highlighted in Section 3.2.3, the sensitivity of the cobalt catalysts to surface hydroxylation was additionally noted.…”

“…For example, Duong and co-workers have used the VISION spectrometer operating at the Spallation Neutron Source at the Oak Ridge National Laboratory (ORNL, USA) to identify the optimal binding of ethyne to a nitro-decorated metal–organic framework compound . Jones and co-workers have used the recently upgraded TOSCA spectrometer to use ethene adsorption on model skeletal cobalt catalysts to characterize the active site distribution . Reminiscent of the work of Kelley and co-workers examining adsorption on Raney nickel, the new cobalt studies revealed the presence of highly active sites that induced adsorbate dehydrogenation.…”
