摘要：Present paper explores the synthesis of nanocomposite NiFe2O4-Fe2O3-NiO and its relevance as liquefiedpetroleum gas sensor. The as prepared material was characterized using Scanning electron microscope and X-raydiffractometer. The X-ray diffraction reveals the formation of nickel ferrite along with ferric and nickel oxides. Theaverage crystallite size of material was found to be 4.62 nm. SEM images exhibit the porous nature of sensingmaterial with a number of active sites. Thick film of material was fabricated using screen printing techniques andwas investigated with the exposition of liquefied petroleum gas. VariatiThe maximum value of sensitivity wasfound 5733 for 4 vol.% of LPG. These experimental results show that synthesized nanocomposite material is apromising material for LPG sensor.
