Direct Hydrogenation of Dinitrogen and Dioxygen via Eley-Rideal Reactions.
Most Eley-Rideal abstraction reactions involve an energetic gas-phase atom reacting directly with a surface adsorbate to form a molecular product. Molecular projectiles are generally less reactive, may dissociate upon collision with the surface, and thus more difficult to prove that they can participate intact in abstraction reactions. Here we provide experimental evidence for direct reactions ...
متن کاملDynamic Deuterium Enrichment in Cometary Water via Eley–rideal Reactions
The deuterium-to-hydrogen ratio (D/H) in water found in the coma of Jupiter family comet (JFC) 67P/ Churyumov–Gerasimenko was reported to be (5.3±0.7)×10, the highest among comets and three times the value for other JFCs with an ocean-like ratio. This discrepancy suggests the diverse origins of JFCs and clouds the issue of the origin of Earth’s oceanic water. Here we demonstrate that Eley–R...
متن کاملKinematics of Eley-Rideal Reactions at Hyperthermal Energies.
Direct or Eley-Rideal reactions between energetic N^{+} and O^{+} projectiles and O atoms, adsorbed onto Pt and Pd surfaces, are studied experimentally at incidence energies between 20 and 200 eV. The exit energies of the diatomic molecular products NO and O_{2} depend linearly on the incidence energy of the corresponding projectiles. A reaction mechanism is proposed, where the incident project...
متن کاملComputer Simulation of Eley-Rideal Reactions over Rough Surface
The effect of surface roughness on an Eley-Rideal reaction mechanism is studied. The rough surfaces are generated over a 2-dimensional square lattice using the random deposition model. In an Eley-Rideal reaction mechanism, a reacting particle approaches from the bulk and reacts with an active site upon collision with it. Three different rough surfaces are considered for the study. Multifractal ...
متن کاملDynamic Scaling for Eley-Rideal Reactions Over Rough Surface
Eley-Rideal reaction mechanism is studied over rough surface of random deposition model. Two types of rough surface are considered: (1) different rough surface with same surface density and (2) different rough surface with different surface density. Dynamic scaling theory, which is generally applied to the growing surface, is applied for this reaction mechanism to obtain the temporal and spatia...
