摘要
通过碱热法制备二氧化钛纳米线,用X衍射仪(XRD)、扫描电镜(SEM)和紫外-可见光分度计对样品进行表征,以甲基橙为模拟污染物,在8 W紫外光照射下考察不同碱溶液的浓度、水热温度和保温时间对二氧化钛纳米线的光催化性能的影响。研究表明采用碱热法制备的Ti O2纳米线,具有较高的光催化活性,其中Na OH溶液浓度为10 mol/L,水热温度为180℃,保温时间为24 h制备的二氧化钛纳米线的光催化性能最好,在光照80 min,降解甲基橙达到了91%。
Titanium dioxide nanowire was synthesized by alkali method. TiO2 samples were diffraction, SEM and ultraviolet visible spectrophotometer. The degradation of methyl orange in characterized by X-ray aqueous solution under 8 W ultraviolet light irradiation was used to evaluate the effect of photocatalytic activity with different alkali solution concentration, hydrothermal temperature and soaking time. The results showed that the all the prepared samples were functioned as a highly active photocatalysts under the irradiation of ultraviolet degradation, with the solution of 10 M NaOH solution concentration, heated at 180℃ for 24 h, the best property of photocatalysis was represented. The percent degradation of MO was ca. 91% under simulated irradiation for 80 min.
