Abstract
TiO2 nanoparticals were prepared by hydrothermal synthesis technique. The thick films of TiO2 were prepared by screen printing technique; gas sensing performance of this film was tested for various gases. The film showed highest response and selectivity to H2S gas. The gas response selectivity of film were measured and presented. The films were characterized by x-ray diffraction (XRD), Scanning Electron Microscopy (SEM), Transmission Electron Microscopy (TEM), Selected Area diffraction and optical absorption spectroscopy technique. The quick response and fast recovery are the main features of these films. The effect of temperature on the optical, structural, morphological and gas sensing properties of the films were studied and discussed.
