摘要：
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. © 2020, Science Press. All right reserved.
