摘要
采用溶胶-凝胶法制备了TiO2/碳纳米短管复合体,利用X射线衍射仪(XRD)、差热-热重分析仪(TG-DTA)、扫描电子显微镜(SEM)和紫外-可见光谱仪(UV-vis)对复合体的过程和微观结构进行了分析,结果表明:短管与钛酸丁酯的质量比为1%,热处理温度为500℃时,光催化降解活性艳红X-3B效果最好,同时TiO2与碳纳米短管的复合造成TiO2的吸收谱线蓝移。
TiO2/short CNTs composite was prepared by the sol-gel method using isopropyl alcohol as the solvent. The composite process and microstructure of TiO2/short CNTs were analyzed by X-ray diffraction, thermogravimetric-differential thermal analysis, scanning electron microscopy and UV-Vis spectra. The results showed that the TiO2/short CNTs composites with 1 % mass ratio of short carbon nanotubes to butyl titanate had the best photoactivity.
