Perovskite type oxides are fascinating nanomaterials and its physical properties of interest to materials science through perovskites include superconductivity, magnetoresistance, ionic conductivity, and a multitude of dielectric properties, which are of great importance in microelectronics and telecommunication. Recently interest has arisen in perovskite-type oxides as catalysts due to high thermal and hydrothermal stability as well as high mechanical strength among other properties. In the present work, LaMn1-xFexO3 perovskite was synthesized by the co-precipitation method. The product was characterized by X-ray diffractometer (XRD), Scanning electron microscope (SEM), Energy dispersive X-ray spectrometer (EDX), Fourier transform infrared spectroscopy (FTIR), UV-visible absorption spectroscopy andconductivity study. The XRD pattern confirmed the formation of perovskite phase. The SEM micrographs indicated thatthe morphology contain porosity due to inter-particle voids. The presence of functional groups of the pure and dopedlanthanum manganite were studied by FTIR. The optical band gap decreases with increasing the content of iron in thesample. The conductivity study confirmed that the conductivity increases with increasing the content of iron.
