The oxidation of ethanol over vanadia supported catalyst was examined.
The monolayer V2O5/TiO2 catalyst demonstrated the best activity in the selective oxidation of ethanol.
The reaction involves reversible reduction of V5+ cations whereas titanium cations remain in the Ti4+ state.
At 100–150 °C acetaldehyde is the main product; at higher temperatures the reaction shifts toward acetic acid.
