摘要：

FTIR study of CO adsorption on Au/TiO2 samples prepared by a deposition -precipitation technique is presented. The absorption spectra of (12) CO and (12) CO -(13) CO mixture are examined at different equilibrium pressures at room temperature. From these data two kinds of chemically active sites, strongly coupled and interacting were evidenced. Chemical effects, depending on the CO coverage, were also observed.
