Dissociation and atom recombination of H2 and D2 on metallic surfaces: A theoretical survey
نویسنده
چکیده
The inelastic and dissociative chemisorption of H, (vj) and D, (vj) on Cu surfaces has been studied in a wide range of collisional kinetic energies below and above the activation barriers to dissociation. The dynamic calculations have been performed within a fully multi-dimensional semiclassical and a two-dimensional quantum wave packet approach. The important aspects concerning the different behaviours of vibrationally excited molecules coming from the gas-phase and dissociating on the surface are presented and discussed. The hydrogen atom recombination via Eley-Rideal mechanism has been also studied and the relevant rate coefficient as a function of the translational temperature of the gas-phase atom has been calculated.

H2‐D2 Exchange Kinetics in the Presence of H2S over Pd4S, Pd70Cu30, and Pd47Cu53 Surfaces
H2S retards H2 transport across Pd membranes used for H2 separation by forming a Pd4S scale that has both low H2 dissociation activity and low H-atom permeability. As hydrogen purification membranes, alloys such as Pd70Cu30 and Pd47Cu53 are attractive alternatives to pure Pd due to their resistance to formation of bulk sulfides. Nonetheless, exposure to H2S can decrease the permeability of Pd70...
متن کاملA Theoretical Study on the Structure-Radical Scavenging Activity of Some Hydroxyphenols
Antioxidants are made for the struggle and reconstruction of the damaged cells, because of their ability in destroying the free radicals. On account of their importance, a theoretical procedure was applied for the study of the molecular structure and radical scavenging activity of six hydroxyphenols which have been introduced as antioxidant compounds. All geometry structures were optimized by M...

متن کاملThe Effect of Cu Impurity on the CO-dissociation Mechanism on the Fe (100) Surface: A Full Potential DFT Study
In this study, the theoretical calculations of CO dissociation were carried out on Cu-Fe alloy surface by a full-potential method, which made more accurate results especially on the prediction of adsorption energies. This process may be governed by either a direct route or a H-assisted via HCO and COH intermediates pathways. In comparison to the pure surface Fe (100), the presence of Cu atom en...

Propene dissociation channels were characterized by ab initio CCSD(T)/6-311++g(d,p) calculations. Inthis work the detailed mechanism of propene dissociation to C2H4+CH2, C2H2+H+CH3, C2H2+CH4 andC3H3+H2+H have been investigated. According to our calculations, ten fragments can be classified intofive dissociated channels. Our results point out that two mechanisms come into play in the H2 eliminat...
