SnO2 nanoparticles coated on carbon nanotubes (CNTs) were prepared via a simple microwave-hydrothermal route. The as-obtained SnO2-CNTs composites were characterized using X-ray powder diffraction, Raman spectroscopy, and transmission electron microscopy. The photocatalytic activity of as-prepared SnO2-CNTs for degradation of Rhodamine B under visible light irradiation was investigated. The results show that SnO2-CNTs nanocomposites have a higher photocatalytic activity than pure SnO2 due to the rapid transferring of electrons and the effective separation of holes and electrons on SnO2-CNTs.
通过简单的微波水热法制备了包覆在碳纳米管（CNTs）上的二氧化锡纳米颗粒。使用X射线粉末衍射、拉曼光谱和透射电子显微镜对所得的二氧化锡-碳纳米管复合材料进行了表征。研究了所制备的二氧化锡-碳纳米管在可见光照射下对罗丹明B降解的光催化活性。结果表明，由于电子的快速转移以及二氧化锡-碳纳米管上空穴和电子的有效分离，二氧化锡-碳纳米管纳米复合材料具有比纯二氧化锡更高的光催化活性。
