英文摘要：

Titannium dioxide （TiO2） and carbon nanotubes （CNTs） are the most investigated functional materials over the past 15 years. TiO2/CNTs nanocomposites, which combine the intrinsic properties and advantages of two materials, have been widely studied in diverse fields. In this paper, the recent progress in synthesis study of TiO2/CNTs are systematically reviewed based on the Latest literatures. Some important synthesis methods such as mixing, chemical vapour deposition, electrospinning, sol-gel, hydrothermal and solvothermal are summarized. The synergistic effects such as enhancing the separation of photo-generated electron/hole pairs, increasing the visible light photocatalytie activity and the specific surface area are discussed. The problems that still should be resolved and the further perspectives are pointed out.
