Abstract

The stability of β-VOPO₄ and (VO)₂P₂O₇ under conditions of n-butane and 1-butene oxidation was investigated using the complementary techniques of in situ laser Raman spectroscopy, X-ray diffraction, and X-ray photoelectron spectroscopy. Both β-VOPO₄ and (VO)₂P₂O₇ demonstrated bulk structural integrity during n-butane oxidation. The relatively greater reducing capacity of 1-butene, however, induced a transformation of β-VOPO₄ to (VO)₂P₂O₇. The presence of V(V) and V(IV) in used β-VOPO₄ and (VO)₂P₂O₇ was detected by X-ray photoelectron spectroscopy for both hydrocarbon oxidation conditions.
