Efficient Photocatalytic Activities of TiO2 Hollow Fibers with Mixed Phases and Mesoporous Walls.

摘要: Currently, Degussa P25, with the typical mixed phases of anatase and rutile TiO2, is widely applied as commercial photocatalysts. However, there are still some obstacles for P25 nanoparticles totally high photocatalytic activities, especially catalytic stability due to their inevitable aggregation when used In present work, we reported exploration a novel TiO2 photocatalyst, which could offer an ideal platform synergetic combination mixed-phase composition, hollow architecture mesoporous walls desired excellent efficiency robust stability. The nanofibers were fabricated via facile single capillary electrospinning technique, in foaming agents creating mesopores throughout fibers. obtained fibers exhibit purity possess 94.6% 5.4% TiO2. As compared as-fabricated exhibited much higher efficient activities stabilities toward hydrogen evolution rate ~499.1 μmol g−1·h−1 ~99.5% degradation Rhodamine B (RhB) 60 min, suggesting promising application
