Nanoferrites gas sensors: A critical review
Gas sensing characteristics of nanoferrites have been critically and comprehensively reviewed along with a discussion on their unique spinel structural and defect characteristics. A special focus on pure as well as doped CoFe2O4, NiFe2O4, ZnFe2O4, CuFe2O4, MnFe2O4. has been given due to their techno...

Summary: | Gas sensing characteristics of nanoferrites have been critically and comprehensively reviewed along with a discussion on their unique spinel structural and defect characteristics. A special focus on pure as well as doped CoFe2O4, NiFe2O4, ZnFe2O4, CuFe2O4, MnFe2O4. has been given due to their technological potential The dependence of gas sensing properties on the gas sensing parameters such as gas concentration, operating temperature, relaxation, and recovery time as well as sensitivity, limit of detection and response etc. The influence of crystallite size, adsorption, chemical surface state, and area of sensor on sensitivity has also been analyzed. A critical review of various reported results on nanoferrites gas sensors towards variety of gases has also been included. Finally, a discussion on future developments in designing integrated nanoferrites gas sensors has been presented.
