To obtain $TiO_2$ inorganic nanofibers, TiP/PVAc solutions were electrospun and calcined. Their microscopic structures and morphologies were characterized using FT-IR, WAXD, and SCM. The effects of the spinning and the calcination conditions on crystal formation and structure were then studied. Also, the specific surface area and the photocatalytic activity of the inorganic fibers wcre examined. The Study revealed that fibers with anatase structure showed higher specific sur/ace area and better photocatalytic activity than fibers with a rutile structure.
