Facile construction of hierarchical ellipsoid-shaped TiO2 porous nanostructures with enhanced photocatalytic activity†
Abstract
Hierarchical ellipsoid-shaped TiO2 porous nanostructures with a high specific surface area and abundant pores are fabricated by the hierarchical assembly of TiO2 nanoparticles via a simple one-pot hydrothermal process. The as-synthesized ellipsoid-shaped TiO2 exhibits significantly enhanced photocatalytic activity for MB degradation compared to P25 under ultraviolet light and sunlight irradiation, respectively.
