A new method is proposed to prepare iron oxide supported on silica pillared phosphates with high surface areas 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 new method have much larger surface areas and pore volumes. The results of X-ray diffraction (XRD) and temperature programmed reduction (TPR) indicate that the samples obtained by this new method have better Fe~2O~3 dispersion than those obtained by conventional method and the dispersion threshold is 0.25 Fe~2O~3/g (SiO~2-ZrP). The pillared materials obtained by the new method show good activities in dehydrogenation of ethylbenzene.
