Реферат: Isotopic oxygen exchange on the surface of Mo-V-Te-Nb oxide catalysts was studied. Catalyst samples contained more than 95% of (i) orthorhombic phase M1, (ii) pseudo hexagonal phase M2, or (iii) layered phase with structure Me5O14 (Me – Mo, V, Nb). Two forms of exchangeable oxygen were found on the surface, i.e. strongly bonded lattice oxygen and relatively weakly bonded adsorbed oxygen. According to in situ studies with isotope 18O adsorbed oxygen leads to deep oxidation products, while lattice oxygen participates mainly in the partial oxidation processes. Weakly bonded oxygen concentration decreases in series: Me5O14 > M2 > M1 and thus selectivity towards partial oxidation increases.
