Summary:TiO[sub.2] has attracted significant research interest, principally due to its nontoxicity, high stability, and abundance. Carbon-doped TiO[sub.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[sub.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[sub.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[sub.2] . The TiO[sub.2] /CNT mesoporous nanomaterials synthesized in this work are possible for clean industrial productions.
