Abstract:
Fourier transform infrared, X-ray photoelectron and extended X-ray absorption fine structure spectroscopy applied were to study the formation and state of components and forms of carbon monoxide adsorption with (Pd+Zr)/SiO2 catalysts obtained from organometallic precursors. Based on the results obtained, a model of active sites assuming direct interaction of highly dispersed palladium particles with surface zirconium ions is proposed. Taking into account the similarity of the adsorptive and catalytic properties of (Pd+Zr)/SiO2 and Pd/ZrO2 systems, which reveal the effects of a strong metal-support interaction (SMSI), the possibility of the application of this model to explain the mechanism of SMSI is discussed.
