Synthesis and Characterization of Nanomagnetic Graphene via Co-Precipitation Technique with Aid of Ultrasound

Abstract:

Graphene nanoplates (GNPs) was immobilized with nanomagnetite using co-precipitation technique with the aid of ultrasound for the production of magnetic graphene nanoplate composite Fe₃O₄/G (MGNC) production. The physico-chemical properties of graphene were compared with the fabricated magnetic graphene composite using different characterization techniques. The crystalline and chemical structures of nanographene before and after magnetic immobilization were identified using X-Ray diffraction. The morphological structure of magnetic composite was identified by using Transmission Electron Microscope (TEM).it was carried out to investigate the precipitation of nanomagnetite onto the nanographene sheets. Atomic Force Microscope (AFM) analysis of magnetic graphene composites confirms the presence of magnetic nanoparticles attached to nanographene. The Vibrating sample magnetometer (VSM) confirmed the superparamagnetic properties of the prepared composite that represented with its hysteresis curve, and the saturation moment per unit mass, Ms for the MGNCs is 22.7548 emu·g−1
