چکیده انگلیسی
In the present study, high-crystalline and well-defined Fe3O4 nanostructures with tunable morphologies were fabricated through a facile one-pot solvothermal approach. The morphology, crystal structure and chemical compositions of the products were characterized at the nanoscale. X-ray diffraction and selected area electron diffraction patterns indicate that the products have a pure spinel phase without the presence of any other impurity. Based on the transmission electron microscope technology, shape evolution of the products were investigated. Several morphologies including irregular particles, clusters, hollow sphere and octahedrons can be obtained by only adjusting the amount of NaOH without using any surfactant. Magnetism investigations show that all the products perform ferromagnetic behavior with high saturation magnetization at room temperature, which mainly originates from their high crystalline nature and template-free fabrication process.
