Popis:	X-ray photoelectron spectra of Te 3d5/2 and Mo 3d5/2 core electrons of TeO2-MoO3 provided an evidence for reduction of Te to the metallic state even in the presence of oxygen in the feed, while the component Mo was rather stable under reductive environment, in the vaporphase oxidation of ethyl lactate at 300 °C. Lattice oxygen was supplied to make up for the oxygen-deficit at the surface, and the catalyst should be used under oxidative, oxygen-rich conditions.
