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 o...
