Using novel compounds for synthesis of metal oxide nanomaterials can tune their physical properties due to the associated variation in the shape, size and crystallinity. In this work, γ-Fe2O3 and Co3O4 nanoparticles were successfully prepared by a facile thermal decomposition route, employing [Fe(C32H22N4O2)]·2H2O and [Co (C16H11N3O4)].1 2H2O complexes, respectively as new precursors. The x-ray diffraction and high resolution transmission electron ... إقراء المزيد
