Abstract

Nanocrystalline NiFe2O4, ZnFe2O4, MgFe, ZnAl, CoAl2O4 and MgAl with spinel structure and average crystallite size in the range of 8-35 nm, were successfully synthesized by citrated sol-gel technique. The structure and phase identification of the prepared powder samples were characterized by X-ray diffraction (XRD) and microstructure by transmission electron microscopy (TEM). The response of prepared spinel-type oxide materials to various reducing gases like ethanol, liquefied petroleum gas, hydrogen sulfide and ammonia was examined. The sensor response mainly depends on the operating temperature and the test gas species. The reasons for the sensing characteristics of spinel-type oxide based sensor elements were discussed.
