The adsorption ofC0 and CO, on platinum. nickel and copper W;IS studied by X-ray and UV photoelectron spectroscopy. The results indicate that CO, is physisorbcd on p!atinum and copper and 1b:it the bonding: of CO on all tbrce metals involves the metal d-electrons and particularly the 5a lcvcl of CO.
Hydrogen, oxygen and cesium adsorption on beryllium metal were modelled using a Bed5 cluster containing seven layers. The ab initio'Hartree-Fock calculations employ effective core potentials and full Dgi, point-group symmetry. Cesiation of the surface is found to lower the work function by 2.2 eV, i
The oxygen coverage was determined by cathodic charging curves at different potentials under the conditions of periodic, low-speed, potentiostatic current potential curves in 1 N HCIO4 with vigorous hydrogen or argon stirring between + 0"6 V and + 1"5 V. t In the case of hydrogen stirring the net cu
