Abstract

Recyclable catalyst using magnetic LaFeO3/Fe3O4 nanocomposite has been successfully synthesized using co-precipitation method. The structural and magnetic properties of the samples were investigated using X-Ray Diffraction (XRD, Brunauer-Emmett-Teller (BET) surface area analysis, and Vibrating Sample Magnetomfeter (VSM) Spectroscopy. The XRD results revealed that the LaFeO3/Fe3O4 nanocomposite shows orthorhombic and cubic spinel structure from LaFeO3 and Fe3O4, respectively. The saturation magnetization of LaFeO3 increases with the increasing of Fe3O4 content in the nanocomposite. The sonocatalytic performance and recyclability of the sample were evaluated by degrading methylene blue (MB) as a model of organic pollutant. Compared to LaFeO3 nanoparticles, the sonocatalytic activity of LaFeO3/Fe3O4 nanocomposite showed better performance. The stability of the catalyst was also checked by removing the catalyst from the MB solution simply using an external magnetic field. The result shows that the sample has good stability.
