A new method for preparing nickel oxide supported silica pillared phosphates with high surface area

A novel procedure was developed to prepare nickel oxide supported silica pi llared zirconium phosphates whose surface areas and d-spacings are 125-198 m(2)/g and 2.1-2.3 nm respectively, whereas the samples prepared by convent ional method only have surface areas less than 20 m(2)/g and d-spacings 1.8 nm. X-Ray diffraction (XRD), N-2 adsorption and temperature programmed red uction (TPR) indicated that the materials obtained by the new method have b etter nickel oxide dispersion than those obtained by the conventional metho d.
