Abstract
High-resolution electron energy loss spectroscopy has been used to study the coadsorption of CO and O on Ni(1Â 1Â 1) and Ni(1Â 0Â 0) surfaces at 250Â K. These vibrational measurements showed that with increasing surface coverage at 250Â K, the preadsorbed O caused changes in the adsorption sites for the after-adsorbed CO molecules revealing, however, dissimilar adsite alterations for the two Ni single crystals. Also, a different behavior towards carbonate formation was found upon CO adsorption at 250Â K on Ni(1Â 0Â 0) and Ni(1Â 1Â 1) surfaces precovered with O at 250Â K.
