Extending the absorption range of TiO2 nanofibers to visible light is a great improvement of the photocatalytic property of TiO2 . In this study, TiO2 /WO3 /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 TiO2 and WO3 respectively. Different volume ratios of the precursors were added to a solution of PVP before electrospinning. The fibers were studied by XPS, SEM-EDX, TEM, FTIR, XRD, Raman spectroscopy and UV-VIS diffuse reflectance spectroscopy (DRS)...
