| Abstract: | Zinc ferrite (ZnFe2O4) nanoparticles have been synthesized at 700°C 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, H2, NO x . SO x , and H2S have been studied. It was found that they exhibit excellent selective sensitivity toward 200 ppm of H2S at the operating temperature of 250°C, and thus this nanosized ferrite is expected to be useful in an industrial application as a potential H2S gas sensor. |
