Electrospun nanofibers for gas sensor application were effectively prepared from polyvinyl alcohol and pluronic solution with different percentages of titanium dioxide ($$\hbox {TiO}_{2}$$TiO2) 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 $$\hbox {TiO}_{2}$$TiO2 nanoparticles to the blended solution increased nanofibers diameters from $$280 \pm 20$$280±20 to $$310 \pm 30\ \hbox {nm}$$310±30nm. The gas sensor response of $$\hbox {TiO}_{2}$$TiO2 nanofibers (as a function of temperature) was estimated toward liquid petroleum gas (LPG), $$\hbox {CO}_{2}$$CO2, and $$\hbox {O}_{2}$$O2 and compared with pure nanofibers. The maximum response value (100%) was obtained for LPG at $$160\,{^{\circ }}\hbox {C}$$160∘C with $$\hbox {TiO}_{2}$$TiO2 nanofibers (0.01%). These results show promising gas sensing characteristics (such as lower operating temperatures and sufficient gas responses) for those nanofibers materials.
