Abstract

The ordered porous zirconium oxide incorporated with variable amounts of titanium was synthesized via a direct-hydrothermal synthesis procedure. Characterizations by powder X-ray diffraction, nitrogen adsorption, high-resolution transmission electron microscopy, and energy-dispersive, X-ray photoelectron, Raman, and diffuse reflectance ultraviolet spectroscopies have been carried out to study the chemical nature of titanium in the porous ZrO₂ material. The results show that titanium ions are homogeneously dispersed into the framework of ZrO₂, when the amount of titanium doping is less than 20 mol %, which is much higher than that in silica-based materials. At higher titanium loading, nanocrystalline TiO₂ anatase is formed. A suitable amount of titanium is favorable to the thermal stability of the porous zirconium oxide.
