New organic‐inorganic hybrid nanofibers, poly(vinyl alcohol) (PVA)‐titanium lactate (TL) hybrid nanofibers, were formed by electrospinning employing water as a solvent. Anatase‐type TiO 2 nanofibers were obtained by calcination of the hybrid nanofibers in air. The fiber diameters of the PVA‐TL hybrid nanofibers was 200–350 nm, and the fiber diameter of the TiO 2 nanofibers was 70–80% of that of the PVA‐TL hybrid nanofibers. The specific surface area and average pore diameter of the TiO 2 nanofiber calcined at 500°C for 5 h were 21.0 m 2 /g and 7.4 nm, respectively. The photocatalytic decomposition of methylene blue using the TiO 2 nanofibers was also investigated. © 2007 Wiley Periodicals, Inc. J Appl Polym Sci 104: 1232–1235, 2007
