Available in PDF, EPUB and Kindle. Book excerpt: The adsorption of carbon monoxide on nickel has been studied by the thermal desorption technique. Thermal desorption peaks for states with activation energies of desorption of 13, 27, and 39 Kcal/mole have been identified. Other weakly adsorbing states were present but the peaks could not be resolved. Preparing the surface by oxidation and reduction and by argon ion bombardment gave thermal desorption curves similar in peak temperatures but not in peak heights. Two effects were noted with the runs where water pressure was appreciable in the system. It was necessary to heat the samples in carbon monoxide to obtain adsorption into the highest energy states and also carbon dioxide was observed with this carbon monoxide peak. These effects were attributed to the oxidation of the surface by the water vapor. It was also necessary to treat the sample strongly to remove carbon near the surface to obtain a stable clean surface. Annealing the ion bombarded surface increased the number of high energy (39Kcal) sites and decreased the number of moderate energy (27 Kcal) sites. The logarithm of the frequency factor was found to be a linear function of the square root of the activation energy for desorption. The presence of hydrogen when carbon monoxide is adsorbed at elevated temperatures gives rise to a new desorption peak between 600K and 700K. (Author).

This book was released on 1990 with total page 53 pages. Available in PDF, EPUB and Kindle. Book excerpt: At one-third coverage of carbon monoxide, a (3 x 3)R30 deg low energy electron diffraction (LEED) pattern has been observed on Ni(111), Pd(111) and Pt(111). Interestingly, the C-O stretching frequency indicates three completely different adsorption sites; a 2-fold bridge site for Ni(111), a 3-fold site for Pd(111), and an on-top site for Pt(111). As the coverage increases to one-half, a c(4x2) Leed pattern appears. For Ni(111) and pd (111), the adsorbate seems to prefer the 2-fold site. On Pt(111), half of the chemisorbed CO sits on the on- top site while the other half is located at the 2-fold site. Further increase in coverage results in titled CO molecules on Pt(111) and adsorption of CO at the on-top site of Ni(111) and Pd(111). To rationalize these observations, we carried out extended Huckel calculations within the tight-binding formalism. Our discussion is augmented by conceptual tools such as density of states and crystal orbital overlap population. We also examine the question of the adequacy of the Blyholder model in describing the adsorbate-surface interaction. (js).
