Effect of tellurium promoter on vanadium phosphate catalyst for partial oxidation of n-butane

Te-promoted （1%） vanadium phosphate catalyst （VPDTe） was prepared via VOPO4·2H2O by calcining its precursor VOHPO4·0.5H2O in a flow of n-butane/air.VPDTe catalyst has resulted a higher existence of V5＋ phase with V5＋/V4＋ ratio of 0.23.SEM micrographs show that Te addition altered the arrangement of...
