Vanadium species supported on inorganic oxides as catalysts for propene epoxidation in the presence of N2O as an oxidant

- Silica support induces the best activity of V species for PO formation when compared to other oxides.
- Formation of VOSi species is crucial in propene epoxidation in the presence of N2O.
- Acidic sites direct propene oxidation to PO isomers or products of total oxidation.
