Enhanced performance of {001} facets dominated mesoporous TiO_2 photocatalyst composed of high-reactive nanocrystals and mesoporous spheres

摘要

{001} facets dominated mesoporous anatase TiO_2 sheets composed of mesoporous spheres and high reactive nanocrystals with exposed {001} facets were synthesized successfully with NH_4F as the capping agent by the hydrothermal and heat treatment method. The photocatalyst exhibits a high specific surface area and a higher photocatalytic activity than Degussa P25 and pure TiO_2 nanosheets in the degradation of organic dyes under UV irradiation.
