Özet

This work investigated the use of Li and Ti codoped NiO nanocomposites as a room temperature (R_T) gas sensor. The nanocomposites were prepared using citrate-gel technique. In order to reduce agglomeration, the polyvinyl alcohol was added as a reducing agent. The thermal analysis of gel composition of Li_0.1Ti_0.018Ni_0.882O (LTNO) was investigated by DTA/TG and phase evolution of as-burnt powder was examined by XRD technique. XRD showed single phase NiO at 500 °C. TEM investigation revealed that the size of particles ranged from 5 to 40 nm. To detect sensor response, final sample was dissolved with minimum amount of solvent and spin coated thin film onto glass substrate with interdigitated gold (Au) electrodes. The film was used to detect toluene, ethanol and chloroform at R_T. The maximum sensitivity was obtained for toluene vapors at R_T.
