Semiconductor TiO2-Al2O3 thin film gas sensors derived from aqueous particulate sol-gel process
Abstract
<p>Nanostructured TiO<sub>2</sub>-Al<sub>2</sub>O<sub>3</sub> films and powders were prepared by a straightforward aqueous particulate sol-gel route. Titanium (IV) isopropoxide and aluminum chloride were used as precursors, and hydroxypropyl cellulose was used as a polymeric fugitive agent in order to increase the porosity. The effect of Al:Ti molar ratio was studied on the crystallization behavior of the products. X-ray diffraction (XRD) revealed that the powders crystallized at 800 °C, containing anatase-TiO<sub>2</sub>, rutile-TiO<sub>2</sub> and cubic-Al<sub>2</sub>O<sub>3</sub> phases. Furthermore, it was found that Al<sub>2</sub>O<sub>3</sub> retarded the anatase to rutile transformation. Transmission electron microscope (TEM) image showed that one of the smallest crystallite sizes was obtained for TiO <sub>2</sub>-Al<sub>2</sub>O<sub>3</sub> binary mixed oxide, being 3 nm at 600°C. Field emission scanning electron microscope (FE-SEM) analysis revealed that the deposited thin films had nanostructured morphology with the average grain size in the range 20-70 nm at 800°C depending on Al:Ti molar ratio. Thin films produced under optimized conditions showed excellent microstructural properties for gas sensing applications. They exhibited a remarkable response towards low concentrations of CO gas at operating temperature of 400 °C.</p>
