Supermicroporous zirconium phosphate materials possessing wormhole-like pores in the size range 1.3-1.8 nm were synthesized by using nonionic poly(ethylene oxide) surfactant (e.g., C{sub 16}H{sub 33}(EO){sub 10}, C{sub 18}H{sub 35}(EO){sub 10}) as a structure directing agent. The textural and structural properties were characterized by powder X-ray diffraction, N{sub 2} adsorption analysis, differential thermal analysis, scanning and transmission electron microscopy, {sup 31}P MAS NMR and infrared spectroscopy. The synthesized materials are amorphous, exhibiting high surface areas, narrow pore size distributions, excellent thermal stabilities (over 800 deg. C) and acidic properties. The supermicropore size of the synthesized zirconium phosphate may be tunable by the variation of alkyl chain length of the surfactant.
