摘要: 以竹活性炭为载体,采用溶胶凝胶法实现催化剂的负载制备了复合型TiO2/AC光催化剂,并采用N2等温吸附、扫描电镜 (SEM)、X射线衍射 (XRD)、热重差热分析法(TGDSC) 、傅里叶变换红外光谱法 (FTIR)等分析手段对其结构进行了表征。结果表明: TiO2的负载使得竹活性炭的比表面积、孔容发生了变化,由改性前的1 181.9 m2/g和0.670 cm3/g 分别降至979.0 m2/g和0611 cm3/g;TiO2以化学键的方式在竹活性炭表面杂乱分布,并且不易脱落;制备的TiO2/AC为锐钛矿晶型,晶粒尺寸为18.4 nm。

Abstract: Bamboo activated carbon(AC)supported TiO2 photocatalyst was prepared by solgel method. The TiO2/AC was characterized by N2 adsorption isotherm, scanning electron microscopy, Xray diffraction, TGDSC, FTIR and etc.. The results showed that the specific surface area and pore volume of AC were reduced from 1 181.9 m2/g and 0.670 cm3/g to 979.0 m2/g and 0.611 cm3/g, respectively after modification. TiO2 was loaded on AC by chemical bond and combined firmly. The average particle diameter of TiO2/AC was 18.4 nm and its crystal form was similar to anatase.
