Abstract

The TiO2NTs with special three-dimensional tubular morphology was prepared by anodic oxidation method, the methods of nonmetal doping, Ti3+ self-doping and semiconductor recombination were used as the modification of TiO2NTs. The contact angles of different samples after modification were measured. The structure and morphology of the samples were characterized by SEM, EDS and XPS, and the influence of different factors on the contact angle of TiO2NTs was investigated. The results show that the hydrophilicity is closely related to the morphology and structure of the material. The special tubular structure of TiO2NTs has a smaller contact angle, and the semiconductor composite will block the nozzle and increase the contact angle to a certain extent. Under the premise of not changing the morphology, doping modification can make TiO2NTs achieve hydrophilicity under visible light.
