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.TiO2 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 TiO2 film were studied by DSC-TGA and XRD.The results indicate that there is an optimum heattreated temperature and the photocatalytic activity of TiO2 film which treated at this temperature is the best.
