| 摘 要： | 通过溶液法合成了PbSe/TiO2复合纳米管,并对其进行了微观形貌、晶体结构等的表征。结果表明,制得的样品是由PbSe和TiO2两种材料构成的复合材料,致密、均匀的TiO2薄膜包覆在PbSe纳米管表面。以氙灯为模拟光源,通过对甲基橙的降解研究了PbSe/TiO2复合纳米管的光催化性能。结果显示,PbSe与TiO2之间形成的异质结使PbSe/TiO2复合纳米管具有较高的光催化性能,比纯PbSe纳米管的催化降解率提高了约4.5倍。另外,对PbSe/TiO2复合纳米管光催化稳定性也进行了研究。

| Abstract: | PbSe/TiO2 composite nanotubes(NTs)are successfully synthesized by solution method.The characterizations indicate the as-prepared samples are composed of PbSe and TiO2.It is found that the surface of PbSe NTs is uniformly coated with a TiO2 thin layer.Under illumination with xenon lamp,the photocatalytic activity is investigated by degradation of methyl orange dye.As a result,PbSe/TiO2 NTs heterostructures display a better photocatalytic degradation rate,almost 4.5 times as high as that of PbSe NTs.Furthermore,the photocatalytic stability of PbSe/TiO2 composite NTs is also studied. |
