Abstract:
The electronic state of copper atoms and ions in the supported copper-alumina catalysts modified with zirconium and cesium oxides is studied by IR spectroscopy using adsorption of CO. The ZrO2 additives are shown to increase the dispersion of the supported metal, stabilize the ionic states of copper, add improve their resistance to reduction with H-2 The Cs2O additives decrease the effective charge of the copper ions and facilitate their fast reduction in the presence of CO and H-2. The effects observed are caused by the variation of the metal-support interaction and the electronic donor-acceptor interaction of copper atoms and ions with the modifying oxide.
