Abstract

Using the methods of diffuse reflectance electron spectroscopy, Raman spectroscopy and temperature-programmed reduction with hydrogen, the formation of surface phases in supported lanthanum-modified V2O5/SiO2 catalysts was studied. It is shown that the order of depositing the active component has a significant effect on the phase composition and catalytic properties of the samples in the reaction of propane oxidative dehydrogenation.
