Inclined N(sub 2) desorption in a steady-state No + CO reaction on Pt(100)

Article Abstract:

The angular and velocity distributions of desorbing products N(sub 2) and CO(sub 2) were studied in a steady-state NO + CO reaction on Pt(100). A contribution of the intermediate N(sub 2)O decomposition pathway was first proposed on this surface and it was found that CO(sub 2) desorption collimated along the surface normal.

Effects of alloying on the chemistry of CO and H(sub 2)S on Fe surfaces

Article Abstract:

Deleterious gases such as CO and H(sub 2)S can cause degradation of steel by reacting with metal surface. The findings suggest that alloying iron with Al or Si is unlikely to increase simultaneously increase its resistance to the initial stages of chemical degradation by CO and H(sub 2)S.

Adsorption, diffusion, and dissociation of H2S on Fe(100) from first principles

Article Abstract:

Spin-polarized density functional theory is employed to characterize hydrogen sulfide (H2S) and HS adsorption, diffusion, and dissociation on the Fe(100) surface. The site preference of H2S, HS and S on Fe(100) is investigated.
