Facile Synthesis of TiO2 Hollow Spheres with Enhanced Photocatalytic Activity
TiO2 hollow spheres were synthesized through a facile bubble-template hydrothermal method.Microscopic and diffraction data indicated that the well-crystallized rutile-phase product was composed of self-assembly nanorods with an average diameter of 35 nm.The as-grown product showed high photocatalytic activities in degradation of organic pollutants such as rhodamine B under UV irradiation.It was found that almost all rhodamine B can be decomposed after only 30 minutes of UV irradiation.The enhanced photocatalytic performances were probably attributed to the structure of TiO2 hierarchical hollow spheres,which supplied higher specific surface area and faster electron transport.
