Abstract: A novel and thermally stable hierarchically porous yttrium doped zirconia material with crystallized framework has been synthesized in a facile process. XRD, nitrogen adsorption analysis, FESEM, FETEM, were used for the structural characterizations. This novel hierarchically porous zirconia shows a well-defined ordered macroporous structure, a broad distributed mesoviods, and a very uniform mesoporous pore-distribution. Small amount of yttrium can be helpful to increase the thermal stability of the prepared hierarchically porous zirconium oxide.
