| Abstract: | Electronic state of the cations of Sn–Sb catalysts has been investigated by the XPS method. The established change in the charge of tin and antimony ions is ascribed to the interaction between catalyst components during its formation. It has been found that the surface of Sn–Sb–O catalysts accumulates antimony, which accounts for their high selectivity in partial oxidation of olefin.
