|Title:||Characterization of Tin Oxide Supported Vanadia & Molybdena Catalysts by Low Temperature Oxygen Chemisorption Technique|
Reddy, B Mahipal
Rao, P Kanta
|Abstract:||Two series of SnO2 supported V2O5 and MoO3 catalysts prepared have been characterized by means of low temperature oxygen chemisorption and X-ray diffraction techniques. Oxygen uptake as a function of loading of V2O5 on V2O5 - SnO2 catalysts increases linearly upto 3.2 wt. % V2O5 and then decreases, whereas on MoO3 - SnO2 catalysts also oxygen uptake increases and reaches a maximum at 3 wt. % MoO3 and thereafter remains constant. These results have been interpreted in terms of patchy monolayer models of V and Mo-oxide phases.|
