Resumen:
In this work we review theoretical calculations and experimetal measurements carried out by our group vor toluene oxidation reactions on V-Antimonate ctalñysts, in order to propose a rection mechanism and to stablish activity-structure relationships.The semiempirical calculations have involved toluene perpendicular and parallel approaches to the different metal cation sites on the clustersurface.On the other hand experimental studies have involved the solid characterization and kinetics measurements of toluene vapor-phase oxidation on V-antimonate catalysts doped with Titanium.Our results provide hulpful indications about the role of oxide metal ions,suggesting that benzaldehyde selectivity is related with the redox properties of the solid. Besides, the whole solid structure appears to be responsible for the catalytic behavior of VSb oxides during toluene oxidation reactions.
