A comparison of NO2 sensing characteristics of α- and γ-iron oxide-based solid-state gas sensors
In this work, we report on the successful synthesis of α- and γ-iron oxide (hematite and maghemite, respectively) nanopowders using a simple sol–gel technique followed by dries in supercritical ethanol. Microstructural and morphological characterizations were performed using X-ray diffraction (XRD)...

| description | In this work, we report on the successful synthesis of α- and γ-iron oxide (hematite and maghemite, respectively) nanopowders using a simple sol–gel technique followed by dries in supercritical ethanol. Microstructural and morphological characterizations were performed using X-ray diffraction (XRD) and transmission and scanning electron microscopies (TEM and SEM). The iron oxide semiconducting materials have been tested as sensing layer in solid-state conductometric planar sensors for the monitoring sof low NO
