Abstract
The organic solvent method to synthesize a highly crystalline VOHPO 4·0.5H 2O was investigated. Firstly, reduction of V 2O 5 in alcohols was studied. It was clear that there existed a quasistable V 4O 9 state after reduction with isobutyl alcohol. When a mixture of isobutyl alcohol and benzyl alcohol was used, the reduction was relatively rapid and difficult to control. Secondly, pure, uniform and roseshaped precursor VOHPO 4·0.5H 2O was obtained by the dehydration-condensation of V 4O 9 and ortho-H 3PO 4 when ortho-H 3PO 4 was added dropwise. The balance in rates between addition of ortho-H 3PO 4 and the dehydration-condensation was important to prepare a uniform precursor.
