Coupling {001} Facets Dominated Anatase TiO₂ Nanosheets with CNTs for Efficient Photocatalyst

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.
