NIOBIUM-DOPED TITANIA NANOPOWDERS FOR GAS SENSOR APPLICATIONS

Pure titania and titania doped with Nb (3%) was synthesised by sol-gel route from alkoxide precursors. The gel obtained was dried to get nanopowders and then calcined at various temperatures. XRD and SEM characterization were made to know the physical properties of these materials. The sensing prope...

Zusammenfassung:Pure titania and titania doped with Nb (3%) was synthesised by sol-gel route from alkoxide precursors. The gel obtained was dried to get nanopowders and then calcined at various temperatures. XRD and SEM characterization were made to know the physical properties of these materials. The sensing properties towards 02 were tested using different concentration of 02 in N2.
