EFFECT OF SYNTHESIS CONDITIONS FOR PHOSPHATED MESOPOROUS ZIRCONIUM DIOXIDE ON FORMATION OF ITS STRUCTURE AND ADSORPTION PROPERTIES

We have used X-ray phase analysis, temperature programmed desorption of argon, and IR spectroscopy to study the conditions and characteristics of formation and the adsorption and acidic properties of mesoporous phosphated zirconium dioxide. We have established that treatment of a mesostructural and mesoporous hydrogel of zirconium hydroxide with a solution of orthophosphoric acid not only promotes stabilization of the mesostructure and the texture when detemplated, but also functionalization of the zirconium dioxide surface.
