Abstract

Mesoporous zirconium phosphate pyrophosphate of composition Zr(P2O7)0.81(O3POH)0.38 was obtained by calcination at 600°C of a mesoporous zirconium phosphite diphosphonate, Zr[(O3P-C6H4-PO3)0.54 (O3P-C6H4-PO3H2)0.13(O3PH)0.79]. The surface area of this completely inorganic material (215 m2/g) was lower than that of its inorgano-organic precursor (350 m2/g); however, both materials exhibited the same pore distribution, with an average pore diameter of ≈4 nm, and similar values of the mesopore volume (0.21 and 0.28 cm3/g, respectively). These results showed that the thermal treatment at 600°C leaves nearly unaltered the mesoporous structure of the precursor. 31P solid state NMR and TEM investigations were also carried out and discussed. The material obtained represents a considerable advancement in the preparation of zirconium phosphates with high surface area. Due to the good thermal stability of its surface acid groups (700–800°C), it is of interest for potential uses as an acid catalyst at high temperature.
