Chemisorption of Sulfur on Iron and Its Influence on Iron-Gas Reactions, Surface Self Diffusion and Sintering of Iron

Atomistic Analysis of the Microbial Influence on the Adsorption Characteristic of Sulfur, Hydrogen, and SO4on Iron Surfaces

“…The low-energy electron diffraction (LEED) and Auger electron spectroscopy (AES) studies for the adsorption of sulfur suggest that the iron surface is saturated with sulfur atoms, even at very low activities of sulfur . The adsorption of sulfur atoms for iron surfaces is listed in Table , and optimized geometries for Fe (100), Fe (110), and Fe (310) are shown in Figure .…”

“…The low-energy electron diffraction (LEED) and Auger electron spectroscopy (AES) studies for the adsorption of sulfur suggest that the iron surface is saturated with sulfur atoms, even at very low activities of sulfur. 46 The adsorption of sulfur atoms for iron surfaces is listed in Table 1, and optimized geometries for Fe (100), Fe (110), and Fe (310) are shown in Figure 3. The hollow (H-1/ 4 ML) site is found to be most stable for adsorption of sulfur at Fe (100) and long bridge (LB-1/4 ML) for Fe (110); however, the deep hollow (DH-1/4 ML) site is most stable for Fe (310) for the sulfur atom shown in Table 1 where ML corresponds to the monolayer.…”
