Titanium-doped ordered porous zirconium oxide

Zirconium oxide containing titanium with ordered pore-arrangement was synthesized by the surfactant-assisted route, under the hydrothermal condition. X-ray powder diffraction, nitrogen adsorption, TEM, UV-VIS spectroscopy and Raman spectroscopy methods were adopted for the study on the synthesized materials. The results show that it is helpful to increase the BET surface areas when the amount of titanium is less than 15 mol%, and that less than 30 mol% of doping of titanium can be successfully incorporated into the framework of zirconium oxide. Nevertheless, the ordering of the pore structure will decrease with the amount of doping and the noncrystal titania will appear on the surface of the pore structure, once the amount of doping is more than 30 mol%.
