In present investigation, lanthanum ferrite was synthesized by citrate-nitrate auto-combustion route. The prepared material was characterized by X-ray diffraction, scanning electron microscopy, UV-vis absorption spectroscopy and differential scanning calorimetry. X-ray diffraction study confirmed the formation of lanthanum ferrite nanocomposite and its average crystallite size was found to be 40 nm. Surface morphology of the sensing material showed the uniform distribution of particles of lanthanum ferrite with large number of pores. These pores act as gas adsorption sites. The optical band gap of the nanocomposite was found to be 4.18 eV. The maximum percentage sensor response for lanthanum ferrite was observed to be 394. (C) 2016 Elsevier B.V. All rights reserved.
