Abstract: The tetrabutyl titanate (TBT) were chosen as raw material,solid titanium dioxide (TiO2) nanofibers were fabricated by combining electrospinning with sol-gel and high temperature carbonization techniques.Subsequently,the different amounts of pore-forming agent diisopropyl azodicarboxylate (DIPA) were added and porous TiO2 nanofibers were fabricated.The morphology and crystal structure of nanofibers were characterized by specific surface area analyzer and so on respectively.The results indicated that the crystal structure of solid TiO2 nanofibers was rutile while porous TiO2 nanofibers was anatase.When the mass fraction of DIPA was 5wt%,the highest degradation efficiency of 50mg porous TiO2 nanofibers on 50ml methylene blue at 3h illumination arrived 91.5%.
