Graphene acts as an excellent supporting material in the preparation of a variety of nanocomposites. In the present study synthesis of LaFeO3/GO was carried out through citrate gel auto combustion method. X-ray diffraction, Field emission scan electron microscopy and Fourier transform infrared spectroscopy were used to study the effect of GO on the structural, magnetic and optical properties. The XRD peak shows that all the diffraction peaks of LaFeO3/GO nanocomposites can be assigned similar to a single phase LaFeO3 belonging to orthorhombic distorted perovskite LaFeO3 phase [1]. The calculated average grain size is in the range of 26 to 45 nm. The synthesized LaFeO3-graphene nanocomposite can be potentially used as a visible-light responsive magnetically separable photo catalyst and hence as a powerful separation tool to deal with water pollution problems.
