摘要
采用溶胶凝胶法制备了玻璃表面上掺杂镧的TiO2薄膜.利用高压液相色谱仪、可见紫外分光光度计和扫描电镜研究了不同镧掺杂量及不同热处理温度对玻璃表面TiO2薄膜光催化降解油酸的影响。
The lanthanum doped TiO 2 films coated on glass surface were prepared by Sol Gel method.The variant doping proportion and heat treatment temperature of TiO 2 films influence on photocatalytic degradation of oleic acid,which were investigated by high pressure liquid chromatography,visible ultraviolet spectrophotometer and scanning electron microscope.As a result,2.5%(La/Ti atomic ratio) of optimal concentration and 400 °C of adaptive heat treatment temperature were obtained.
