โœฆ Synopsis

A chemisorbed species of CO, has been observed on Pd( 1 IO) in the presence of coadsorbed water. It has been identified using vibrational spectroscopy as a bent, negatively charged CO;-species which has previously been observed on a number of clean and alkali metal predosed surfaces. The donation of negative charge from water to the palladium surface is identified as the key factor in the formation of CO:-, The catalytic implications of this observation are discussed.

We study the CO chemisorption on epitaxial Pd and Pt monolayers grown on W (110), by using a simple tight-binding self-consistent recursion method model. The tr donation, "rr back-donation and the adsorption energy are reduced by the substrate presence. For the atop site above Pd/W (110), however, t

The desorption of CO, produced by the interaction of oxygen adatoms and CO admolecules on Pd( 110) was studied with angle-resolved thermal desorption. Four peaks of CO, formation appeared in the different coverage and temperature range. The desorption flux shows sharp and anisotropic angular distrib
