Synthesis, Characterization and Photocatalytic Application of LaFeO3 ,NdFeO3 Magnetic Nanocomposites in Removal of Organic Wastes Water

The development in the field of nano scale science and engineering provides us with unprecedented understanding and control of matter at atomic and molecular levels. The later advances in nanotechnology allow us to make more and more advanced materials with unusual magnetic, electric, optical, and biological properties [1] Organic dyes are widely used in different fields and seriously decrease water pollution. Most of the industrial dyes are toxic, carcinogenic, and teratogen [2]. Photocatalysis can play an important role in new technologies of water and wastewater purification [3]. The present work shows preparation of LaFeO3 ,NdFeO3 nanocomposites as effective photocatalysts. The prepared products were characterized by x-ray diffraction pattern (XRD).Transmission electron microscopy (TEM) and Fourier transfer infrared (FT-IR) spectroscopy. Alternating gradient force magnetometer (AGFM) illustrates magnetic behavior of LaFeO3, NdFeO3 nanocomposites. The photocatalytic behavior LaFeO3 ,NdFeO3 nanocomposites were evaluated using the degradation metile violet, malachite under ultraviolet light irradiation .the results show that LaFeO3 ,NdFeO3 nanocomposite have application magnetic and photocatalytic performance
