Using electrospinning, specially prepared Ti and Sr precursor TiO 2 / SrTiO 3 composite nanofibers were successfully fabricated. This would ensure the close and uniform contact between TiO 2 and SrTiO 3 , which significantly contributes to the electrons transfer at the interface between the two semiconductors with different band gaps. Meanwhile, the long fibrous structure of TiO 2 / SrTiO 3 composite nanofibers would further ease the electron transfer, enlarge the specific surface area, and enhance the light absorption capability thus leading to the improvement of photocatalytic efficiency. Because of the above‐mentioned advantages, the TiO 2 / SrTiO 3 composite nanofibers exhibited higher photocatalytic H 2 generation efficiency over bare TiO 2 nanofibers in a water/methanol sacrificial reagent system under the irradiation of UV light.
