This paper concerns the physicochemical properties and activity in NO decomposition of a rutile-supported V-O-Mo catalyst, obtained by sol–gel method. Rutile, o-MoO3 and β-MoO3 are the main phases found by XRD and TEM. Monolayer vanadia-like species containing some Mo atoms substituted for V ones are present on molybdena crystallites. These species show some activity in NO decomposition to N2 and O2. An increase in this activity with the increase of O2 content in the feed indicates surface reconstruction occurring due to interaction with oxygen.
