Synthesis of a copper ferrite system (CuFe2O4) via chemical co-precipitation method is characterized by X-ray diffraction, surface morphology (scanning electron microscope) and optical absorption spectroscopy. These characteristics show their dependence on the relative compositions of the two subsystems. They are further confirmed by the variation in the band gap. A study of gas sensing properties shows the spine! CuFe2O4 synthesized in 1:1 molar ratio exhibit best response to LPG adsorption/resistance measurement. Thus resistance based LPG sensor is found robust, cheap and may be applied for kitchens and industrial applications. (c) 2012 Elsevier Ltd. All rights reserved.
