Synthesis of CuO Microspheres by the Simple Hydrothermal Method and their Optical Absorption Properties

Abstract:

CuO microspheres with a diameter range of 1~3 μm are successfully synthesized with 1 m mol CuCl2 as copper source and 3 m mol Na2CO3 as auxiliary salt at 180 °C for 24 h via the easy hydrothermal method. The phase, the morphologies and optical absorption properties of the samples have been characterized and analyzed by XRD (X-ray diffraction), SEM (Scanning electron microscope) and ultraviolet-visible absorption spectroscopy (UV-VIS), respectively. XRD analysis shows that the phase of as obtained samples is CuO. SEM analysis confirms that the increase of the the auxiliary salt is in favor of the synthesis of CuO microrods. And UV-VIS measurements show that CuO microspheres have a good optical absorption property.
