The cause for the shift of diffraction peaks is that the amount of Bi intercalated into anatase TiO2 is larger than that into brookite TiO2 under the same conditions.

在同样的条件下，Bi插入锐钛矿TiO2的量多于其插入板钛矿TiO2的量，从而导致部分X射线衍射峰向高角度方向稍微移动。

The morphology and microstructure characteristics of the apertured silver doped TiO2 microtubes were characterized by means of the X-ray powder diffraction, thermal analysis, transmission electron microscopy, scanning electron microscopy, X-ray photoelectron spectroscopy and N2 absorption.

氮吸附的结果显示该样品具有很高的比表面积，银的修饰没有显著影响二氧化钛微管的孔结构； XRD的表征结果显示，银修饰的二氧化钛多孔微管具有良好的锐钛矿晶型； XPS的分析结果表明银以游离的金属态存在； TEM的观测结果显示，银团簇沉积于二氧化钛纳米晶粒的表面。

While in photoreduction of Cr , the titania-modified MCM-41 photocatalysts were more photoactive than the titania-silica composite (25％ TiO〓).

在光催化降解苯酚中氧化钛修饰MCM-41的光催化活性虽然不及结晶的锐钛矿相纳米氧化钛，但是仍具有较高的催化活性；在光催化还原Cr到Cr反应中氧化钛修饰MCM-41的光催化还原性明显高于部分结晶的TiO〓-SiO〓（25wt％TiO〓）复合氧化物。
