| 摘 要： | 采用水热法制备了二氧化钛纳米管-石墨烯的复合光催化剂。利用X射线衍射仪、扫描电镜、透射电镜和拉曼光谱仪对复合材料进行了表征与分析,并对其光催化性能进行了测试。结果显示,同纯二氧化钛纳米管相比,二氧化钛纳米管-石墨烯的光催化性能较高。石墨烯与二氧化钛纳米管复合,充当电子受体,载流子迁移率得到提高,从而提升了光催化性能。

| Abstract: | A photocatalyst of titanium dioxide nanotube-graphene was prepared by hydrothermal method in this paper. The composites were characterized for further analyzation by X-ray diffractometry, scanning electron microscopy, transmission electron microscopy and Raman spectroscopy. The photocatalytic properties were tested. The results show that the photocatalytic performance of titanium dioxide nanotube-graphene is higher than that of pure titanium dioxide nanotubes. Graphene is combined with titanium dioxide nanotubes to act as an electron acceptor, and the carrier mobility is improved, thereby improving photocatalytic performance. |
