Abstract
The influence of modifying additives of Ce, Zr, La and Cs oxides on the electronic state of palladium supported on γ-Al2O3 has been studied by IR-spectroscopy of adsorbed CO, diffuse reflectance UV–visible spectroscopy, X-ray diffraction (XRD) and H2 chemisorption. The modified supports have been prepared using impregnation, coprecipitation and sol–gel methods. It is established that Ce and Zr oxide additives increase the effective charge of palladium ions whereas La and Cs oxides lower it. The effect of metal–support interaction is stronger in samples prepared by sol–gel than by coprecipitation
