| Abstract: | A simple and available method is proposed for the synthesis of cobalt-containing nanoparticles. This method comprises cobalt formate thermolysis in hydrocarbon oil without extra stabilizing ligands. The size, composition, and structure of the nanoparticles are determined by transmission electron microscopy, X-ray powder diffraction, and electron diffraction. The average particle size is 10–14 nm. The major components are cobalt oxides CoO and Co3O4. Apart from these oxides, the particles contain minor metallic cobalt. |
