Abstract :
TiO2 and Ru-doped TiO2 nanofibers were fabricated by calcining electrospun TiO2-PVP hybrid fibers at 600 °C. Their humidity and O2 sensing properties were investigated. The morphologies of nanofibers were characterized by scanning electron microscopy (SEM), which showed that the nanofibers with diameter of 260 nm formed a non-woven mat structure. Phase structures of the nanofibers were characterized by X-Ray difractometer (XRD) which showed that TiO2 nanofibers are polycrystalline with a mixture of anatase and rutile structure at 600°C. The effects of Ru doping in TiO2 sensing properties were investigated. The results show that humidity and O2 gas sensing properties of TiO2 nanofibers are effectively enhanced by Ru doping.
