Microwave-assisted synthesis and characterization of hexagonal Fe3O4 nanoplates

Hexagonal magnetite (Fe3O4) nanoplates with an average edge length of 80 nm were successfully prepared in large quantities by a facile microwave-assisted route. The influences of experiment parameters such as reaction time, microwave power, and concentration of NaOH and other additive agents on the morphology and size of final products were investigated in detail. Phase structure, morphology and magnetic properties of products were carefully studied by X-ray diffraction (XRD), transmission electron microscopy (TEM), selected area electron diffraction (SAED), high-resolution transmission electron microscope (HRTEM), and vibrating sample magnetometer (VSM). Magnetic studies revealed that hexagonal Fe3O4 nanoplates have low saturation magnetization of 36.4 emu/g and the possible reason has been proposed.
