HYDROTHERMAL SYNTHESIS OF COPPER OXIDE NANOPARTICLES AT SUPERCRITICAL CONDITIONS

Ultra fine copper oxide nanoparticles were synthesized by using a supercritical hydrothermal method. The produced nanoparticles had an average size of 1.6 nm, and were characterized by X-ray diffractometery (XRD), transmission electron microscopy (TEM),nitrogen gas adsorption test (BET) for measuring of the surface area and temperature programmed reduction analysis (H2-TPR) for evaluation of the catalytic activity. The results demonstrated appreciable potential of the hydrothermal supercritical methods for the synthesis of inorganic metal oxides.
