| Abstract |
| In recent years, there has been a renewed interest on spinel ferrites for their remarkable versatile applications.
Among AFe2O4, zinc ferrite (ZnFe2O4) has gained special importance due to its application in gas sensing, drug
delivery and magnetic resonance imaging. Nanocrystalline powder of ZnFe2O4 with average size of 25-30 nm was
synthesized using citrate-gel method. Thermogravimetric analysis and XRD confirmed the formation of nanocrystalline
ZnFe2O4 at 400oC. The band appearing below 700 cm–1 in the FTIR spectrum confirmed the presence of Zn(Fe-O)
group. Microstructural investigation was done on SEM and TEM. The response of ZnFe2O4 towards alcohol and
acetone vapour at 350oC was studied. The sample showed n-type conductivity with excellent vapour sensitivity. |
