摘要

通过溶液法合成了PbSe/TiO

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TiO

两种材料构成的复合材料，致密、均匀的TiO

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/TiO

复合纳米管的光催化性能。结果显示，PbSe与TiO

之间形成的异质结使PbSe/TiO

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/TiO

复合纳米管光催化稳定性也进行了研究。

Abstract

PbSe/TiO

composite nanotubes (NTs) are successfully synthesized by solution method. The characterizations indicate the as-prepared samples are composed of PbSe and TiO

. It is found that the surface of PbSe NTs is uniformly coated with a TiO

thin layer. Under illumination with xenon lamp

the photocatalytic activity is investigated by degradation of methyl orange dye. As a result

PbSe/TiO

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/TiO

composite NTs is also studied.
