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.
