Synthesis of Single-Crystalline Octahedral Co3O4 with Solid-State Thermal Decomposition

Document Type: Research Paper



In this paper, single crystalline octahedral Co3O4 with dimensions about 100–500 nm and
smooth surface has been prepared by solid-state thermal decomposition of cobalt(II) Schiff
base complex Co((3,4-MeO-ba)2 en)Cl2 as new precursor at 450ºC under air atmosphere for
3.5 h. Surface morphology of the products were characterized by Fourier transform infrared
spectroscopy (FT-IR), X-ray powder diffraction (XRD) and scanning electron microscopy
