摘要:
为通过绿色合成途径制备高结晶度且高比表面积的TiO2光催化剂，以胰蛋白胨为模板，采用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，得到具有多孔结构的锐钛矿相TiO2，比表面积为156.338 m2/g，光照120 min后降解率达到93.22%，样品结晶度及活性艳蓝KN-R的光催化降解效果均得到提高．
Abstract:
To produce TiO2 photocatalysts with high crystallinity and high surface area through a green synthesis method, authors utilized the tryptone as template, and produced the TiO2 powders with porous structure bya sol-gel method. X ray diffraction, laser particle analyzer, N2-adsorption desorption, transmission electron microscopy, ultraviolet visible diffuse reflectance, laser scanning confocal microscopy and thermogravimetry techniques were used to characterize the samples. And the photocatalytic performance of the sample by the effect of UV light photocatalytic degradation of reactive brilliant blue KN-R was evaluated. The results showed that after the removal of tryptone template by calcination, the TiO2 in the anatase phase with porous structure is obtained, the crystallinity of sample is improved, the specific surface area is 156.338 m2/g, and the efficiency of photocatalytic degradation of reactive brilliant blue KN-R is improved, after illumination for 120 min the degradation rate reaches 93.22%.
