Preparation of TiO/WO/C/N Composite Nanofibers by Electrospinning Using Precursors Soluble in Water and Their Photocatalytic Activity in Visible Light.

Extending the absorption range of TiO nanofibers to visible light is a great improvement of the photocatalytic property of TiO. In this study, TiO/WO/C/N nanofibers were prepared by electrospinning using precursors soluble in water then annealing in argon. Titanium(IV) bis(ammonium lactato)dihydroxide (TiBALDH) and ammonium metatungstate (AMT) were used as the precursor for TiO and WO respectively.
