Conditions and features of formation, adsorptive and acid properties of phosphated mesoporous zirconium dioxide were studied by XRD, TPDA and IR-spectroscopy methods. It was established that phosphoric acid treatment of mesostructured and mesoporous hydrogel of zirconium hydroxide favors not only mesostructure and texture stabilization upon detemplation, but also functionalization of the surface of zirconium dioxide.


Key word phosphated mesoporouse zirconium dioxide, preliminary acid treatment, mesostructure stabilization, acid-
ity, thermostability.
