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)...
