摘要：

The adsorption of CO at room temperature on a Ru/SiO2 catalyst has been studied by means of FTIR spectroscopy. Spectral evidence for formation of water molecules and a quantity of very dispersed ruthenium on the catalyst surface during CO adsorption was found. On the basis of these experimental results a new reaction scheme for the interaction of CO with a silica-supported ruthenium catalyst is proposed.
