摘要:

为通过绿色合成途径制备出高结晶度且高比表面积的TiO2光催化剂,以胰蛋白胨为模板,通过溶胶凝

胶法制备了具有多孔结构的TiO2粉体.用X射线衍射仪、激光粒度仪、N2-吸脱附、透射电镜、紫外可见漫反

射、激光共聚焦显微镜和热重等技术对样品进行表征,并通过对活性艳蓝KN-R的紫外光催化降解效果评价样

品的光催化性能.结果表明,煅烧法去除胰蛋白胨模板后,得到锐钛矿相且具有多孔结构的TiO2,样品结晶

度提高,比表面积为156.338 m2/g,提高了活性艳蓝KN-R的光催化降解效果,光照120 min后降解率达到

93.22%.

Abstract:

Here, a simple, green, and cost-effective methodology is reported for photocatalyst

materials. A novel porous TiO2 is synthesized by sol-gel method with biological molecular as

templates. The TiO2 is characterized by X-ray diffraction, laser particle size analyzer, N2

adsorption-desorption, transmission electron microscope, diffuse reflectance UV-visible,

confocal laser scanning microscopy and thermogravimetric analysis. The results show that the

TiO2 has high crystallinity and large surface areas (156.3 m2/g). The photocatalytic activity

of the TiO2 is evaluated by decomposing reactive brilliant blue KN-R and the degradation rate

is 93.22 % after 120 min illumination.
