The purpose of this article is to study the photocatalytic properties of doped titanate nanotubes prepared by hydrothermal treatment using different metals: Ce, Fe, Zn and Zr at 2 wt% content. The textural and morphological properties of the nanopowders were determined by different analysis techniques such as: XRD, RD/UV–Vis, FTIR and TG-DTA. The results of the characterizations showed that nanotubes can be obtained with a hollow structure, and an important thermal stability of whatever element nature. However, the photocatalytic activity ends with the photodegradation under UV-Visible irradiation of the three industrial molecules: Malachite Green, Methyl Orange and Tannic Acid having different molecule charges. It was noted that the degradation rates of the order of 98% were obtained in fairly short times. The final results obtained revealed that the dopant nature and the solution pH play a major role in determining the photocatalytic degradation of pollutants using TiNTs. However the application of TiNTs and doped TiNTs show that these materials have an inhibitory power of fungi and bacteria quite important.
