采用溶胶－凝胶法制备TiO2溶胶，负载于Al3O2表面，采用Ar-N2气氛焙烧法制得掺氮纳米TiO2薄膜；运用X射线粉末衍射仪（XRD）、扫描电镜（SEM）和紫外一可见漫反射吸收光谱等技术，考察不同焙烧温度和负载次数对其性能的影响。研究结果表明：200℃、250℃和300℃热处理的样品的晶相为锐钛矿相，350℃时开始出现金红石相，且随温度的进一步升高，金红石相的含量逐渐增多；掺氮的TiO2样品具有可见光吸收性能，250℃热处理的样品达到最佳，其吸收边红移至600nm. 翻译如下：请达人帮助修改一下： a series of nitrogen-doped nano-TiO2 films, coated on glass microballoons bysol-gel method, were prepared by sintering in a NH3 atmosphere. The as-synthesized films were characterized by XRD, SEM and UV-Vis diffuse reflectance spectroscopy,etc. The experimental results showed that, XRD patterns indicated that crystalline phase of the samples sintered at 200°C, 250°C and 300°C are anatase. When sintered beyond 350°C, rutile TiO2 was produced and increased with the heating temperature. The UV-Vis diffuse response spectroscopy showed that all of the nitrogen-doped samples absorbd visible light obviously. The sample sintered at 250°C exhibited a comparative excellent absorption property, which has red-shifted well into visible region up to 600 nm. 请指正：1，下划线的句子感觉没有准确表达, 2,粗线的句子中etc的用法有点奇怪 3，斜体的句子感觉有些重复（表明） [ Last edited by ld12 on 2009-9-19 at 10:50 ] |

| The TiO2 sol was prepared by sol-gel method and coating at Al2O3 surface. The N-doped TiO2 nano-film was sythesized by calcining under an atmosphere of Ar-N2 . The effect of different sintering temperature and times of coating on the properties of the samples was charactertized by XRD, SEM and UV-vis diffuse reflectance and absorption spectra. The results reveals as follows: The samples are anatase phase when heated at 200℃, 250℃ and 300℃; rutile phase appeared in the sample when heated at 350℃; the fraction of rutile phase increased as the temperature rised; the N-doped TiO2 sample could absorb the visable light, and the one heated at 350℃ was the optimum, the absorption edge of which red shifts to 600 nm. |
