INS and IR discriminate the role of OH and H- for acetylene Semi-hydrogenation over ceria

In Situ Vibrational Spectroscopy Provides First Direct Evidence for the Roles of Hydrogen Species in Selective Hydrogenation over Ceria

March 1, 2020

In situ inelastic neutron scattering (INS) and IR spectroscopy provide the first direct evidence for the catalytic roles of cerium hydride (Ce-H) and hydroxyl group (OH) groups in acetylene hydrogenation over ceria as a function of the density

Illustration of step sites as active sites for isopropanol conversion. The less stable of a STO facet, the more step sites created via surface reconstruction and hence reached a higher overall reaction rate.

Illustration of propane oxidative dehydrogenation pathways on the catalyst surface and in the gas phase.

Harnessing Radical Chemistry for Propane Oxidative Dehydrogenation over Boron-based Catalysts

March 1, 2020

Direct experimental evidence of gas-phase methyl radicals in propane oxidative dehydrogenation (ODHP) combined with density functional theory (DFT) calculations uncovers the mechanism behind the exceptional selectivity to olefins over BN catalysts

Towards new super heavy elements

February 1, 2020

Scientists from ORNL and several Japanese laboratories have developed an experimental method for fast determination of the optimum heavy-ion beam energy for the synthesis of super heavy elements.
