Physicochemical and Antibacterial Evaluation of TiO 2 /CNT Mesoporous Nanomaterials Prepared by High-Pressure Hydrothermal Sol-Gel Method under an Ultrasonic Composite Environment.

TiO 2 has attracted significant research interest, principally due to its nontoxicity, high stability, and abundance. Carbon-doped TiO 2 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 2 /CNT mesoporous composites were prepared by the sol-gel method in an ultrasonic environment. Characterized by SEM and TEM, the composite materials contained TiO 2 nanoparticles as well as CNT. After phase analysis, it was the anatase-doped phase. The following infrared light absorption performance and Escherichia coli bactericidal performance tests showed that it had better infrared and visible light absorption performance than pure TiO 2 . The TiO 2 /CNT mesoporous nanomaterials synthesized in this work are possible for clean industrial productions.
