Abstract

High-reactive {001} facets dominated anatase TiO2 nanosheets were synthesized successfully by a simple hydrothermal method. CNTs were used to couple with as-prepared TiO2 nanosheets to further improve the photocatalytic activity of TiO2. Photocatalytic activities of the photocatalysts were tested by the degradation of Rhodamine B (RhB) aqueous solution under the xenon lamp irradiation. The results indicate that the introduction of CNTs will improve the photocatalytic activities of TiO2 which can be ascribed to the enhanced light absorption and separation efficiency of photogenerated holes and electrons. There was also an optimal content of CNTs to modify TiO2, and a possible mechanism for this idea was also proposed.
