Structure effects of benzene hydrogenation studied with sum frequency generation vibrational spectroscopy and kinetics on Pt(111) and Pt(100) single-crystal surfaces

Article Abstract:

Sum frequency generation vibrational spectroscopy and gas chromatography (GC) are used to investigate benzene hydrogenation at high temperatures to determine its structure. Benzene hydrogenation on the Pt(100) and Pt(111) single crystal surfaces show at least two reaction pathways and that benzene hydrogenation does not proceed through cyclohexane and the rate determining step for this pathway is the addition of the first hydrogen atom to adsorbed benzene for both single crystal surfaces.

Benzene intermediates and mechanisms during catalytic oxidation on the Pt(111) surface using in-situ soft X-ray methods

Article Abstract:

Benzene catalytic oxidation on the Pt(111) surface is characterized by using a combination of soft X-ray absorption spectroscopies at the C-K-edge. A mechanism is developed using both UHV and in-situ elevated-pressure experiments and the combination of UHV and in-situ soft X-ray methods has provided in-depth information on the mechanisms and intermediates for benzene catalytic oxidation on the Pt(111) surface.
