Electrospun nanofibers for gas sensor application were effectively prepared from polyvinyl alcohol and pluronic solution with different percentages of titanium dioxide (\(\hbox {TiO}_{2}\)) nanoparticles. Nanofibers membrane was subject to detailed analysis by scanning electron microscopy (SEM), Fourier transform infrared spectroscopy (FT-IR), and thermal gravimetric analysis (TGA). Adding \(\hbox {TiO}_{2}\) nanoparticles to the blended solution increased nanofibers diameters from \(280 \pm 20\) to \(310 \pm 30\ \hbox {nm}\). The gas sensor response of \(\hbox {TiO}_{2}\) nanofibers (as a function of temperature) was estimated toward liquid petroleum gas (LPG), \(\hbox {CO}_{2}\), and \(\hbox {O}_{2}\) and compared with pure nanofibers. The maximum response value (100%) was obtained for LPG at \(160\,{^{\circ }}\hbox {C}\) with \(\hbox {TiO}_{2}\) nanofibers (0.01%). These results show promising gas sensing characteristics (such as lower operating temperatures and sufficient gas responses) for those nanofibers materials.
