【摘要】 采用溶胶-凝胶法制备了TiO2薄膜,以10mg/L甲基橙为目标降解物,研究了焙烧温度、镀膜层数、紫外线光照时间对TiO2薄膜光催化性能的影响。实验结果表明,焙烧温度为500℃,镀膜层数为三层所制得TiO2薄膜光催化活性最好,并且具有稳定、持续的降解效果。更多还原

【Abstract】 TiO2 thin films were prepared by sol-gel method.The influences of calcining temperature and coating layer and the UV illumination on the photocatalytic activities of the TiO2 thin films were investigated using 10mg/L methyl orange as target degradation substance.The experimental results showed that the TiO2 thin films had the highest photocatalytic activity when calcining temperature was 500℃ and three layers.The photocatalytic activities of the TiO2 thin films were steady and lasting.更多还原
