Abstract: Silica-supported catalysts of cation composition V0,3Mo1Te0,23Nb0,12 are produced using slurry method with the nature of the initial compound for the support (TEOS, silica sol, silica gel, aerosil) being varied. The synthesized catalysts are characterized via nitrogen thermodesorption, chemical and X-ray analysis, and high resolution electron microscopy. Catalytic properties are studied in the reaction of ethane oxidative dehydeogenation at a temperature of 400°С in a reaction mixture with the composition С2Н6 : О2 : N2 = 10 : 10 : 80 (vol %). It is found that samples obtained with silica gel display the greatest activity, due to the formation of nanodomens of active phase M1 in the amorphous support matrix and its partial dispersion.
