✦ Synopsis

Abstract

Using carbon nanotubes (CNT) as templete, CNT/ZnO nanocomposite was prepared by a sol‐gel method. Its structure was characterized by XRD, IR and TEM. The UV absorbing properties were detected by a UV spectrophotometer. Photo degradation of methyl red in aqueous solution was investigated by using CNT/ZnO nanocomposite as photocatalyst. The results showed that the nanocomposite was composed of carbon nanotubes coated evenly by ZnO particles, with a diameter of 50–60 nm. UV‐vis spectra indicated that the as‐prepared CNT/ZnO nanocomposite had absorption of visible light as well as ultraviolet light. 60% CNT‐added nanocomposite had the highest degradation rate for methyl red under the sunlight irradiation.
