Abstract

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.
