摘要
为增强二氧化钛的光催化性能,用水热法制备TiO_(2)-Ag_(2)S-rGO三元复合物并将其整理到棉织物上,以赋予棉织物自清洁性能。对制备的三元复合物进行XRD分析,并对整理后的棉织物进行SEM分析。探究钛酸四丁酯的用量、合成温度、合成时间以及体系pH值对三元复合物光催化性能的影响,并通过正交试验以得到最佳试验工艺。结果表明,三元复合物合成并成功附着在棉织物上;最佳试验工艺为:合成温度160℃、合成时间9 h、体系pH值为7以及钛酸四丁酯浓度为0.13 g/mL;光照4 h后,TiO_(2)-Ag_(2)S-rGO三元复合棉织物上的亚甲基蓝基本消失,验证了织物的自清洁性能。
In order to enhance the photocatalytic performance of titanium dioxide,the TiO_(2)-Ag_(2)S-rGO ternary complexes were successfully produced by hydrothermal method and transferred onto cotton fabrics to realize its selfcleaning properties.The prepared ternary complexes were analyzed by XRD and SEM for the finished cotton fabric.The effects of the amount of tetrabutyl titanate,reaction temperature,reaction time and system pH on the photocatalytic performance of the ternary complexes were investigated,and the best experimental process was obtained by orthogonal experiments.The results show that the ternary complex is synthesized and successfully attached to the cotton fabric.The best experimental process is as follows:the synthesis temperature is 160 ℃,the synthesis time is 9 h,the pH of the system is 7 and the concentration of tetrabutyl titanate is 0.13 g/mL.The methylene blue on TiO_(2)-Ag_(2)S-rGO ternary composite cotton fabric basically disappears after 4 h illumination.
