采用多壁碳纳米管(MWCNTs)为原料,分别以异丙醇钛(TIP)、丙氧基钛(TPP)和四丁氧基钛(TNB)为钛源,苯作为溶刺,制备了CNT/TiO2复合材料.利刖N2吸附等温线,扫描电子显微镜(SEM),X-射线衍射(XRD),能量分散性X-射线分析(EDX)以及紫外吸收光谱对所制CNT/TiO2复合材料进行了表征.并在紫外光照射下,通过亚甲蓝(MB,C16H18N3S·Cl·3H2O)水溶液的转,变测试了CNT/TiO2复合材料的光催化性能.研究结果表明:CNT/TiO2复合材料对MB的降解作用不仅有MWCNT的吸附性和TiO2的光催化性,而且还有MWCNT和TiO2之间的电子转移性.
CNT/TiO2 composites were prepared using multi-walled carbon nanotubes (MWCNTs) as a starting ma-terial, and titanium(Ⅳ) isopropoxide, titanium(Ⅳ) propoxide and titanium(Ⅳ) n-butoxide as titanium sources and benzene as a solvent. The composites were characterized by N2 adsorption, scanning electron microscopy, X-ray diffrac-tion, energy dispersive X-ray analysis, and UV-vis absorption spectroscopy. The photoactivity of the prepared materials tion. It can be found that the MB removal effect of the CNT/TiO2 composites is not only due to the adsorption of MWC-NTs and the photocatalytic degradation of TiO2 but also to electron transfer between MWCNTs and TiO2.
