Preparation and characterisation at vanadium phosphorus oxide catalysts for butane oxidation to maleic anhydride
Vanadium phosphate catalysts have successfully been prepared in aqueous media using hydrogen. The catalysts precursors obtained were poorly crystalline VOHPO<sub>4</sub>.05H<sub>2</sub>O and a minor amount of an impurity detected by a reflection in the XRD pattern. Activating...

| Summary: | Vanadium phosphate catalysts have successfully been prepared in aqueous media using hydrogen. The catalysts precursors obtained were poorly crystalline VOHPO<sub>4</sub>.05H<sub>2</sub>O and a minor amount of an impurity detected by a reflection in the XRD pattern. Activating these materials for n-butane oxidation show low selectivity of MA (5%), which could be attributed to the presence of V(V) phases after activation. |
