Abstract
A new low-cost and simple synthesis of titanium phosphate functional materials of desired composition has been developed. The synthesis is based on the heterogeneous interaction between phosphoric acid and the solid (NH4)2TiO(SO4)2 · Н2О precursor. The influence of the synthesis conditions on the titanium phosphate composition has been thoroughly studied using NMR, FT-IR spectroscopy, XRD, DTA techniques and mechanism of TiP formation has been established. Optimal synthesis conditions to provide obtaining of a pure TiO(OH)(H2PO4) · H2O (TiHP) phase have been found.
