Influence of alcohol solvents on characters of VOHPO4·0.5H2O prepared from V4O9 and ortho-H3PO4 Original Research Article

The influence of alcohol solvents on the characters of VOHPO4·0.5H2O, precursor of (VO)2P2O7, prepared from V4O9 and ortho-H3PO4 was studied. Valence of vanadium, XRD, SEM, TG/DTA, 31P-NMR and Raman spectra were used for characterization. Depending on the alcohol solvent used, not only the morphology of particles, but also bulk and surface characters of the precursor VOHPO4·0.5H2O were influenced.
