Steps as adatom sources for surface chemistry: oxygen overlayer formation on Ag(110)

Density Functional Theory Study of the Oxygen Chemistry and NO Oxidation Mechanism on Low-Index Surfaces of SmMn2O5 Mullite

“…Under high oxygen pressure conditions in typical diesel engines, 30 it is likely that other surface active sites will also contribute to the overall activity. A systematic and comprehensive study of SmMn 2 O 5 surfaces taking into account both surface stability and catalytic activity is still lacking to our best knowledge.…”

Two‐Dimensional Adatom Gas Bestowing Dynamic Heterogeneity on Surfaces

“…At 700 K the 2D vapor pressure of the catalytically important metals Pd, Cu, and Ag results in adatom densities ranging between 1 and 6 % on the surfaces of Mo and W (Figure 1 c). [18,22] Although the decisive role of adatoms in the formation of reconstructions, [23][24][25] orienta- Figure 1. Island-terrace morphology of a surface covered by an island of adatoms.…”

Adsorption, diffusion, and vibration of oxygen onAg(110)

“…As the most corrugated surface among the low-Miller-index surfaces of Ag, the (110) surface's interaction with gas molecules such as oxygen proceeds via such fundamental physical processes as adsorption and dissociation. For accurate manipulation of such gas-surface interactions [5][6][7], and of the oxidation reactions of CO [8,9] and hydrocarbons [10] on Ag(110), it is essential to understand the subsequent STM study has strongly suggested that, upon adsorption of O, Ag(110) undergoes added-row reconstruction on the step edges along the [001] direction [21]. Similarly, LEED and Helium-diffraction measurements together with phonon-dispersion calculations [22] and low-energy ion-scattering measurements complemented by Monte Carlo simulation of the ion trajectories [23] [24][25][26][27][28].…”
