(a) The hydrogen production photocatalyzed by the as-fabricated mesoporous TiO2 hollow nanofibers as well as p25 under different irradiation times. (b) Reusability experiment for photocatalytic H2 generation of mesoporous TiO2 hollow nanofibers and p25. (c) Photocatalytic degradation of RhB (C0 = 10 mg/L) of mesoporous TiO2 hollow nanofibers and p25 under UV-visible light irradiation. (d) The plot of ln(C0/C) with irradiation time for mesoporous TiO2 hollow nanofibers and p25. (e) The proposed mechanism for the enhanced photocatalytic activities of the mesoporous TiO2 hollow fibers with mixed phases of anatase and rutile.
