摘要
Hierarchically porous anatase Ti02 microspheres composited with carbonaceous species （TCS） have been successfully fabricated by a one-step template-free solvothermal method, combined with subsequent low temperature dried process. In this configuration, the TCS microspheres are constructed by the intercon- nected porous nanosheets, which are further assembled with abundant nanoparticles and carbonaceous species. Such composite microspheres possess a large specific surface area of 337 m2 g-l, uniform mesopores of 3.37 nm and high total pore volumes of 0.275 cm3 g-1. The materials exhibit the enhanced photocatalytic properties and stability for degradation of rhodamine B （RhB） under visible-light irradiation. The enhanced photocatalytic degradation performance may be ascribed to their abundant porous structure, large specific surface area and the unique assist-function of the carbonaceous species.
