Green synthesis of CdFe2O4 nanoparticles and their application for vapor sensing
Journal Title: Carbon - Science and Technology - Year 2013, Vol 5, Issue 1
Abstract
The work reported about preparation of nanocrystalline CdFe2O4 through an combustion method and characterization of their microstructural, morphological and gas sensing properties. The structural properties investigated by X-ray diffraction revealed with CdFe2O4 cubic structure. Crystallite size was found to be ~ 64 nm. The morphological study characterized by scanning electron microscopy and transmission electron microscopy. The sensor fabricated from these nanocrystalline CdFe2O4 exhibits high sensitivity and rapid response/recovery to ethanol at 350 °C. The sensitivity was up to 59.23 % when the sensor was exposed to 50 to 200 ppm ethanol and the response and recovery time is about 40 and 50 s respectively. The linear dependence of sensitivity on the ethanol concentration was found in the range 50-200 ppm. Hence studies revealed that nanocrystalline CdFe2O4 can be used as sensing material for fabricating high performance ethanol sensors.
