摘要：A green low temperature (90 degrees C) route was proposed for the synthesis of CuO nanoflakes, using CuCO3 center dot Cu(OH)(2) powder and H2O2 aqueous solution (6 vol.%) as the starting materials. The characterization results from X-ray diffraction, Fourier transform infrared spectroscopy and field emission scanning electronic microscopy revealed that the as-synthesized product was pure monoclinic phase CuO nanoflakes. UV-vis absorption spectrum showed that the as-synthesized CuO nanoflakes had an optical band gap of about 2.15 eV. The present method points out a promising green, simple, low cost and low temperature way of converting the natural malachite ore (whose composition is CuCO3 center dot Cu(OH)(2)) into multifunctional CuO nanomaterials.
