Thermal decomposition of HSCH(sub 2)CH(sub 2)OH on Cu(111): Identification and adsorption geometry of surface intermediates

Article Abstract:

X-ray photoelectron spectroscopy is employed to study the surface intermediates from the thermal decomposition of HSCH(sub 2)CH(sub 2)OH on Cu(111) at elevated temperatures. On the basis of the core-level binding energies of C, O, and S as a function of temperature, it is found that HSCH(sub 2)CH(sub 2)OH decomposes sequentially to form -SCH(sub 2)CH(sub 2)OH and -SCH(sub 2)CH(sub 2)O-.

Adsorption and reaction of SO2 with a polycrystalline UO2 film: Promotion of S-O bond cleavage by creation of O-defects and Na or Ca coadsorption

Article Abstract:

The interactions of molecular sulfur dioxide (SO2) with a polycrystalline uranium dioxide film are studied to characterize UO2 for its possible use in desulfurization applications. The reactivity of oxygen-deficient UO2 and sodium- and calcium-precovered UO2 is attributed to charge transfer into the antibonding LUMO of the adsorbed molecule.
