A New Method for Preparing Iron Oxide Supported on Silica Pillared Zirconium Phosphates with High Surface Areas

A Flew method is proposed to prepare iron oxide supported on silica pillared phosphates with high surface alias by impregnating iron species on the precursor of silica pillared zirconium phosphates (APS-ZrP).
 

Compared with samples made by conventional method, samples prepared by the flew method have much larger surface area and pore volumes. The results of X-ray diffraction and temperature programmed reduction indicate that the samples obtained by this new method have better Fe₂0₃ dispersion than those obtained by conventional method and the dispersion threshold is 0.259 Fe₂O₃/g(siO₂-ZrP). The pillared materials obtained by the new method show good activities in dehydrogenation of ethylbenzene.
