Low temperature oxygen chemisorption: a facile technique for characterization of vanadium oxide catalysts supported on anatase and rutile polymorphs of TiO2
Abstract
Oxygen chemisorption at –78 °C has been determined on the reduced surface of vanadium oxide catalysts supported on anatase and rutile modifications of TiO2; a correlation is found between oxygen chemisorption capacities with the activity of the catalysts for vapour-phase oxidation of methanol to formaldehyde.
