Manouchehri, P. Kameli, H. Salamati] Co3O4/CoO nanoparticles have been synthesized by a simple method which is based on the ball-milling and calcination of cobalt acetate and citric acid. The samples were characterized using X-ray diffraction, transmission electron microscope, and Fourier transform infrared spectroscopy. The results show that Co3O4 nanoparticles with an average particle size of ∼40nm can be obtained by calcination of ball-milled precursors at relatively low temperature (350 °C) for 3hours. It should be noted that it is possible to control the size of Co3O4 particles by calcination temperature, calcination time and also by ball-milling duration using this method. Meanwhile, the pure CoO nanoparticles were obtained successfully by thermal decomposition of Co3O4 at 950 °C and quickly quenching to liquid nitrogen.
