Abstract Vanadyl polyphosphates with a P/V ratio=2 (crystalline α-VO(PO3)2 and β-VO(PO3)2 as well as amorphous VO(PO3)2) were synthesized, starting from usually prepared precursor VO(H2PO4)2 but pursuing new methods using V2O5/H3PO4 as well as VOHPO4·1/2 H2O/H3PO4, too. The products were characterized by chemical analysis and X-ray diffractometry.In situ ESR spectroscopy was used as a tool to predict their catalytic activity in the ammoxidation reaction.
