摘    要:通过液相沉积法(LPD)在玻璃片表面制备TiO2薄膜,并以甲基橙溶液为污染液,通过探讨制备TiO2薄膜原料的摩尔比例、诱导晶、沉积温度及时间,以及热处理温度及光照时间等因素对甲基橙溶液降解率的影响,得出最佳的降解条件.研究得出:(NH4)2TiF6与H3BO3摩尔比例为1∶1~1∶6,TiO2诱导晶为0~0.1g,沉积温度为25~65℃和沉积时间24h范围内,最佳降解条件为:摩尔比为1∶6,诱导晶为0.06g,沉积温度为55℃,550℃热处理,适当的沉积及光照时间.

关 键 词:TiO2薄膜  液相沉积  光催化降解  甲基橙

Abstract:TiO2 thin films were prepared on glass slide by liquid phase deposition method.Methyl orange solution was used as the contaminated liquid to test the degradation rate of methyl orange solution by TiO2 thin films.The effects of molar ratio of raw materials for the preparation of TiO2 thin films, induced crystal, deposition temperature, deposition time, heat treatment temperature and illumination time on the degradation rate were tested.The experimental conditions were set to the mole ratio of (NH4)2TiF6 to H3BO3 was 1∶1-1∶6, induction of crystal was 0-0.1 g, deposition temperature was 25-65 ℃, deposition time was 24 h.Experimental results show that the best degradation conditions was that the mole ratio of (NH4)2TiF6 and H3BO3 was 1∶6, induction of crystal was 0.06 g, deposition temperature was 55 ℃, the heat treatment temperature was 550 ℃, appropriate deposition and illumination time.
Keywords:TiO2 thin film  liquid phase deposition  photocatalytic degradation  methyl orange
