Nanostructured Fe doped ZnO: TiO2 for gas sensors applications
Nanostructured Fe doped ZnO: TiO2 with crystalline framework and porous structure were successfully synthesized by hydrothermal route, using ionic and non-ionic surfactants as templates. The structure morphology, surface chemistry and sensing properties were investigated. The results highlighted that ZnO: TiO2 materials show a wurtzite type structure with TiO2 anatase phase in higher proportion, while a minor phase TiO2 rutile was observed for the materials containing Fe. Surface chemistry revealed the elements quantitatively detected on the surface and their chemical environment. Nanostructured Fe doped ZnO: TiO2 materials were sensitive to toxic gases as CO and NO2 at 300 oC and to a small gas concentration in the range of ~3ppm.
