In situ studies of atomic , nano-and macroscale order during VOHPO 4 · 0 . 5 H 2 O transformation to ( VO ) 2 P 2 O 7

Transformation of VOHPO4·0.5H2O precursor to well-crystallized (VO)2P2O7, for n-butane oxidation to maleic anhydride was studied by in situ Raman and XRD techniques. Atomic scale changes observed in the precursor structure at 583 K provided new insights into its transformation to (VO)2P2O7. In addition to (VO)2P2O7, nanocrystalline oxidized -VOPO4 invisible… (More)
