Ti-Si composite materials are mixed at atomic scale, and Ti-O-Si bond appears in all of the samples with different TiO2 content; the mixed oxides are mainly existed in the form of amorphous pattern, anatase appears when the TiO2 content is more than 80%, but compared with the intension of pure TiO2, it has not integrate structure. The acetic content has great influence in the specific area and crystal structure of the mixed oxides. 20TiSi has good heat stability, still possesses 11m2/g after calcined at 1100℃; calcinations on the large scale of temperature does not cause the break of Ti-O-Si bond, TiO2 is well dispersed in 20TiSi calcined at 1100℃, and it still existed in the form of amorphous.

结果表明：制得的Ti-Si复合氧化物具有很高的比表面积，在TiO_2含量为10％时达到681.5m~2／g，Ti原子进入Si-O四面体结构中，形成Si-O-Ti键，复合氧化物的稳定性好，当TiO_2含量低于60 wt％时，以无定型形式存在；当含量为80％时，出现锐钛矿型TiO_2，但与纯TiO_2相比晶型不完整：醋酸对Ti-Si复合氧化物的比表面积、晶型都有很大的影响；TiO_2含量为20％的20TiSi经1100℃高温焙烧后，仍有较高的比表面积(11m~2／g)，稳定性好，在较宽的温度范围内焙烧，没有引起Ti-O-Si键的断裂，分散度高，没有出现晶型TiO_2。

The crystalline size was estimated to be around 13.3-20 nm. Raman spectra indicated there coexisted other phases and a transformation from brookite to anatase in the samples doped with 0.2% Sb.

掺入适量的Sb后，由于Sb替代了TiO2的部分Ti形成Sb-O-Ti结构，改变了TiO2的晶格结构，改善了薄膜的结晶效率，使锐钛矿结构的TiO2：Sb含量明显提高。

Under the visible light catalysis, along with hard content's increase, the methyl orange degeneration rate increases gradually, when TiO2/the Fe2O3 compound proportion is 20:2, has the anatase structure catalysis effect to be best, the degeneration rate achieves 87.2%, but when the compound proportion surpasses 20:2, the degeneration rate drops.

在可见光的催化下，随着铁含量的增加，甲基橙的降解率逐渐增加，TiO2/ Fe2O3复合比例为20：2时，具有锐钛矿型的结构催化效果最佳，降解率达到87.2%，而当复合比例超过20：2时，降解率有所下降。

He TiO_2 crystal grains conglutinate and distribute uniformly on slide in the form of multi-crystal anatase phase.

iO_2晶粒以多个锐钛矿相晶体(晶粒在10nm左右)的形式附着在玻璃片上，且分布相对均匀。

With increasing the annealing temperature, the crystal structure changes from anatase to rutile and the crystallite size increases.

随着热处理温度升高，晶体结构由锐钛矿晶相向金红石晶相转化，同时微晶的颗粒尺寸增加。

The effects of thepreparation conditions on the structures and performances of the sol samples were studied,followed by investigating the formation mechanism of the anatase TiO_2 particles. Thecharacterization of the as-obtained sol-gel samples shows that the TiO_2 and P-doped TiO_2sols have anatase crystal structures, and the latter has higher crystallizability than theformer.

通过对TiO_2溶胶进行微观结构表征，发现：TiO_2溶胶和掺磷TiO_2溶胶均呈锐钛矿晶型，颗粒呈梭形，分散性较好，后者的结晶度更高；两者在可见光区均有较大的光吸收，最大吸收波长为550nm，磷的加入使得TiO_2的禁带宽度变大。
