Innovative TiO 2/SnO 2 nanofibers were fabricated via electrospinning an innovated precursor solution and used for photocatalytic H 2 generation. The nanofibers exhibited greatly enhanced H 2 evolution rate compared to bare TiO 2 nanofiber and P25. The enhanced efficiency of the TiO 2/SnO 2 nanofibers was attributed to its excellent synergistic properties: (1) its good mesoporosity; (2) the red-shift of absorbance spectra to enhance light absorbance capability; (3) its long nanofibrous structure and (4) anatase TiO 2 - rutile TiO 2 - rutile SnO 2 ternary junctions favorable for the separation of electrons and holes. Based on our experimental results, the optimum ratio of TiO 2/SnO 2 nanofibers with 3% Sn demonstrated the highest efficiency in H 2 generation.
