eng	Physico-chemical properties and catalytic behaviour in propane ODH of mesoporous vanadosilicate prepared by Pluronic P123 templating route	In this contribution, we focus on catalytic behaviour of mentioned material in ODH of propane and its comparison with common catalysts prepared by impregnation of vanadium precursor into mesoporous SBA-15 silica. All catalysts were characterized by XRF, N2-BET, H2-TPR, Raman and UV-Vis spectroscopies. The catalytic behaviour was investigated in ODH of propane at 540 °C in reaction mixture consisting of 2.5 mol. % of O2 and 5 mol. % of propane in helium. Characterization results showed that solvothermal synthesis led to higher population of tehrahedral oxo-vanadium monomeric complexes in comparison with impregnation. Difference in catalytic behaviour was not so dramatic like in ODH of n-butane indicating significant differences in active sites for both mentioned reactions.	catalytic activity; ODH; propane; mesoporous; vanadosilicate
