F. Boccuzzi et al., VIBRATIONAL INVESTIGATION OF CO ADSORBED ON GOLD DEPOSITED ON TIO2, Journal of electron spectroscopy and related phenomena, 64-5, 1993, pp. 241-250
FTIR study of CO adsorption on Au/TiO2 samples prepared by a depositio
n -precipitation technique is presented. The absorption spectra of (12
) CO and (12) CO -(13) CO mixture are examined at different equilibriu
m pressures at room temperature. From these data two kinds of chemical
ly active sites, strongly coupled and interacting were evidenced. Chem
ical effects, depending on the CO coverage, were also observed.
