| 摘 要： | 以钛酸正丁酯为先驱体,乙醇为溶剂,盐酸为催化剂,以溶胶凝胶法制备TiO2溶胶,并将其负载于经纯化处理的碳纳米管上,再经不同温度煅烧获得TiO2复合光催化剂。用红外光谱对TiO2煅烧及负载前后进行结构表征,考察了光照条件下溴酚蓝的降解率。采用溶胶-凝胶及负载方法获得CNT-TiO2光催化剂并且明显提高了TiO2光催化效果。加入光催化剂的溴酚蓝容易在20min时降解率达到89%,远高于未负载前的46%的降解率。经比较,400℃煅烧的CNT-TiO2光催化剂的光降解效果相对较好。

| Abstract: | Titania sol was synthesized via sol-gel method that tetrabutyl titanate was the precursor,ethanol as the solvent and hydrochloric acid as the catalyst.Then,the TiO2 sol prepared was loaded on the purified carbon nanotube followed by calcinating at different temperature.The structure of calcinated and loaded TiO2 before and was characterized by IR spectra,and the degradation rate of bromophenol blue was studied under the irradiation of daylight.The results show that CNT-TiO2 catalyst can be prepared by being... |
