Zinc ferrite (ZnFe 2 O 4 ) nanoparticles have been synthesized at 7001C using sodium chloride as a growth inhibitor. Single-phase formation of spinel zinc ferrite having crystallite size in the range of 15-20 nm was observed by XRD and confirmed by TEM. In the present work, the gas-sensing properties of these zinc ferrite nanoparticles toward ethanol, LPG, H 2 , NO x . SO x , and H 2 S have been studied. It was found that they exhibit excellent selective sensitivity toward 200 ppm of H 2 S at the operating temperature of 2501C, and thus this nanosized ferrite is expected to be useful in an industrial application as a potential H 2 S gas sensor.
