AbstractNanocrystalline ZnO-TiO2 (with molar ratios 9:1, 7:3, 1:1, 3:7 and 1:9) were successfully synthesized by hydrothermal method. Synthesized materials were examined with the help of X-ray diffraction and transmission electron microscope. Liquid petroleum gas sensing characteristics of the ZnO-TiO2 films were investigated at different operating temperatures. The ZnO-TiO2 thick film (with 1:1 molar ratio) exhibited good response toward liquid petroleum gas as compared to other investigated compositions. Further, liquid petroleum gas sensing characteristics of CuO modified ZnO-TiO2 thick films were investigated. 0.2 M CuO modified ZnO-TiO2 thick film exhibited excellent liquid petroleum gas sensing characteristics such as higher response (~ 1637.49 at 185 °C) with quick response time (~30 s), low recovery time (~70 s), excellent repeatability and stability at low operating temperature.

Composition Structure

In this research, the pure and Cu-doped SnO2 nanostructure layers covered on the glass substrate by sol-gel and spin coating methods. The composition, structure and surface morphology of these layers have been studied by energy dispersive X-ray spectrometry (EDX), X-ray diffraction (XRD) and field emission scanning electron microscope (FESEM), respectively. The results of EDX analysis show that the Cu-doped SnO2 layer is a mixture of 4.97 wt% Copper and 95.03 wt% Tin elements. The images obtained from FESEM show existence of the particles about 50 nm and 38 nm for pure and Cu-doped SnO2 layers, respectively. Also the results obtained from XRD spectroscopy show that these layers have the tetragonal polycrystalline Tin dioxide structure. The response of these layers investigated for different concentrations of Liquid petroleum gas (LPG) by static gas sensing system. The results of this investigation show that the Cu-doped SnO2 nanostructure layer compared with the pure SnO2 nanostructure layer has the better response for LPG.

The background of work carried out highlighting on polyaniline, N-substituted polyaniline and acid-doped polyaniline. The problems associated with this polymer and promises it hold are also discussed. It also provides introduction to the nanocomposites of polyaniline/nanoclays, and polyaniline/polyacrylic acid. As well, we have described the polymer stabilized intrinsically conducting polymer composites. The state of the art polymer stabilised intrinsically conducting composites have been reviewed. At last, we have reviewed on the CH4 gas sensing since it has been recognized as one of the inflammable gas sensors. The main problem on the CH4 gas sensor lies on its room temperature operation and detection of low ppm level concentration.
