热处理温度对TiO2薄膜光催化活性影响的研究

Effect of heat-treated temperature on photocatalytic activity of TiO2 film

摘要: 采用溶胶-凝胶法及浸渍提拉法,在普通玻璃载玻片上制得了TiO2薄膜,通过差热分析仪及X射线衍射仪分析了热处理温度对TiO2的晶型、晶粒大小、孔隙率及薄膜的光催化活性的影响,结果表明存在一个最佳的热处理温度范围,在这一温度范围内薄膜的光催化活性最好.

Abstract: TiO2 thin film was prepared on glass substrate by sol gel and dip coating method.The effect of heat treated temperature on the particle size,crystal type,porosity and the photocatalytic activity of TiO2 film were studied by DSC-TGA and XRD.The results indicate that there is an optimum heat treated temperature and the photocatalytic activity of TiO2 film which treated at this temperature is the best.
