description | TiO<sub>2</sub> has attracted significant research interest, principally due to its nontoxicity, high stability, and abundance. Carbon-doped TiO<sub>2</sub> can improve light absorption efficiency. In order to prepare high-efficiency photocatalysts, carbon-doped composites were prepared by hydrothermal reaction in a high-pressure reactor, and then TiO<sub>2</sub>/CNT mesoporous composites were prepared by the sol–gel method in an ultrasonic environment. Characterized by SEM and TEM, the composite materials contained TiO<sub>2</sub> nanoparticles as well as CNT. After phase analysis, it was the anatase-doped phase. The following infrared light absorption performance and <i>Escherichia coli</i> bactericidal performance tests showed that it had better infrared and visible light absorption performance than pure TiO<sub>2</sub>. The TiO<sub>2</sub>/CNT mesoporous nanomaterials synthesized in this work are possible for clean industrial productions. |
