| Popis: | TiO2 and Ru-doped TiO2 nanofibers were fabricated by calcining electrospun TiO2-PVP hybrid fibers at 600 o 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 600o 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. |
