Determination of surface sites for hydrogen chemisorption over Mo(100) single crystal surfaces by using LEED, TDS and HREELS

New vibrational data was used in conjunction with LEED and TDS results to propose a structural model for H 2 chemisorption on clean and sulfided Mo(100) surfaces. Above half saturation H atoms adsorb on bridge sites on the unreconstructed surface, but at lower coverages reconstruction takes place an...

Zusammenfassung:New vibrational data was used in conjunction with LEED and TDS results to propose a structural model for H 2 chemisorption on clean and sulfided Mo(100) surfaces. Above half saturation H atoms adsorb on bridge sites on the unreconstructed surface, but at lower coverages reconstruction takes place and new bond sites are created.
