Transmission infrared spectroscopy of methyl- and ethyl-terminated silicon(111) surfaces

Article Abstract:

Transmission infrared spectroscopy (TIRS) was used to investigate the surface-bound species formed in the two-step chlorination/alkylation reaction of crystalline (111)-oriented Si surfaces. Alkyl C-H stretch modes were assigned to the Si-H stretching and bending motions, resulting from H-termination of surface atoms that did not form Si-C bonds during the ethylation reaction.

Infrared spectroscopic investigation of CO adsorption on silica-supported nickel phosphide catalysts

Article Abstract:

The surface chemistry of CO on reduced and sulfided Ni2P/SiO2 catalysts is investigated with infrared (IR) spectroscopy. The IR spectroscopic data for the adsorption of CO on Ni2P/SiO2, and sulfided Ni/SiO2 catalysts correlate well with the trend of HDS activity of the catalysts.
