摘要:
以钛酸四丁酯为前驱体、尿素为氮源,采用溶胶-凝胶法制备N掺杂TiO2。通过X射线衍射(XRD)、傅里叶变换红外光谱(FT-IR)、紫外-可见漫反射光谱(UV-Vis DRS)、扫描电子显微镜(SEM)和热重(TG)对其进行表征,考察了不同硝酸体积配比、U-T摩尔比和热处理温度对样品的晶相结构、表面基团、形貌和光吸收性能等的影响。结果表明在较为温和的条件下,N成功掺杂进TiO2晶格中,所制备的N掺杂TiO2为锐钛矿相和金红石相的混晶结构,拓宽了其光吸收波长范围,扩展了TiO2的应用范围。
Abstract:
N-doped TiO2 was prepared through the sol-gel method with tetrabutyl titanate as the precursor and urea as the nitrogen source. The N-doped TiO2 was characterized by X ray diffraction (XRD), Fourier transform infrared spectroscopy (FT-IR), UV-Vis diffuse reflectance spectroscopy (UV-Vis DRS), scanning electron microscope (SEM) and thermogravimetry (TG). The effects of different nitric acid volume ratios, the U-T molar ratios and the heat treatment temperatures on the crystal phase structure, surface groups, morphology and light absorption properties of the samples were investigated. Results show that N was successfully doped into the TiO2 lattice under relatively mild conditions, and the prepared N-TiO2 has the mixed crystal phase structure of the anatase phase and the rutile phase, which broadens its light absorption wavelength range and extends the application scope of TiO2.
