利用表面活性剂辅助途径，水热条件下合成了含钛的有序多孔氧化锆．通过ＸＲＤ、Ｎ２吸附、ＨＲＴＥＭ、ＵＶ－ＶＩＳ吸收光谱、Ｒａｍａｎ光谱等手段对不同按量的钛掺杂多孔氧化锆进行研究．结果表明，＜１５ｍｏｌ％的钛掺杂有利于提高材料的比表面积；钛掺量＜３０ｍｏｌ％时，钛能很好进入氧化锆骨架中，但随着掺量增加，孔道有序性降低．掺量＞３０ｍｏｌ％，多余的钛将以纳米晶ＴｉＯ２形式析出．
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 obtained show that it is helpful to increase the BET surface areas when the
amount of titanium is less than 15mol%, and that less than 30mol% 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 30mol%.
