Formation of Promoted Sites From Ni(CO)4 Decomposition on Sulfided Mo/Al2O3 Catalysts. A Comparative Ir Study With Conventional Ni-Mo/Al2O3 Catalysts, Using CO as a Probe Molecule

Autor: J.C. Duchet, M. Angulo, Jean Claude Lavalley, Françoise Maugé

Publikováno v: Bulletin des Sociétés Chimiques Belges. 96:925-930

IR spectroscopy has been used to characterize samples prepared by decomposition of nickel carbonyl over a MoS2/γ-Al2O3 based catalyst. IR spectra of adsorbed CO indicates a much higher degree of promotion than for the conventional Ni-Mo/Al2O3 cataly

Sulfided CO-mo/AL2O3 Catalysts: Carbon Monoxide Chemisorption and Surface Structures

Autor: N. J. Tilliette, Daniel Cornet, M. Cornac, J. Bachelier, J.C. Duchet, Jean Claude Lavalley

Publikováno v: Bulletin des Sociétés Chimiques Belges. 93:743-750

The interaction between Co and Mo ions has been examined on a series of Co-Mo/Al2O3 catalysts with constant Mo (6.3 % MoO3) and variable Co concentrations (0.5 - 4.3 % CoO) by comparison with Co/Al2O3 and Mo/Al2O3 catalysts. The type of surface struc

Infrared Investigation of the Acid and Basic Properties of a Sol−Gel Prepared MgF2

Autor: Stefan Wuttke, Alexandre Vimont, Erhard Kemnitz, Marco Daturi, Jean-Claude Lavalley

Publikováno v: The Journal of Physical Chemistry C. 114:5113-5120

This Article reports the use of FTIR spectroscopy of adsorbed probe molecules for the characterization of the acidity and basicity of sol−gel prepared MgF2. The CO adsorption shows that this material possesses 3-, 4- and 5-fold coordinated unsatura
