In this paper, we fabricated a new material based on the lanthanum (La) and vanadium (V) co-doped TiO2 by the sol-gel method, then used La and V codopant TiO2 power materials to fabricate the thin film type gas sensor by the screen-printing technology. Finally, we tested gas sensing response properties for different gases. We found La and V co-doped TiO2 simultaneously possess the La and V doping double characterization. In particular, the La and V co-doped samples showed a good response to formaldehyde, only slightly influenced by presence of benzene.
