Sonication Assisted Synthesis of LaFeO₃/Fe₂O₃/Activated charcoal Nanocomposite for Photocatalytic Degradation of Methylene Blue Dye

The pure nano LaFeO3 and Fe2O3 is prepared by solution combustion method using glycine as fuel and activated charcoal by thermo-chemical activation method. A ternary nano composite of all these three components is then prepared by simple sonication method. The prepared nano composite is characterized by XRD, UV-Visible spectroscopy, SEM and EDS. The effectiveness of the prepared nano composite is then studied for photocatalytic degradation of methylene blue dye. The results showed that the prepared composite material degraded 5 ppm methylene blue solution by about 56% in two hours under visible light irradiation.
