Controlled Systhesis, Characterizaiton And Property Ivestigation Of Cu-Containing Nanomaterials

Cu-containing nanomaterials have important applications due to their unique magnetic, optical absorption, chemical activity, thermal resistance, melting point and other properties.By using CuCl2 and NaOH as the reactants, The hierarchical CuO flocculus-like architectures had been successfully achieved at low temperature. The butterfly-like and flower-like hierarchical CuO structures were synthesized by the same method.It was found that the morphology of nanoplates could be controlled by adjusting initial concentration of reactants, aging time and different synthesis methods. In addition, the hierarchical CuO flocculus-like architectures could electrochemically charge and discharge with more notable hydrogen storage capacities of 100 mAh/g at room temperature.By using CuCl2 and NaOH as the reactants, Cu2O nano/microstructures with cube-like, sphere-like and octahedron-like morphologies were synthesized by using an ultrasonic method at room temperature. It was found that the morphology of nanoplates could be controlled by adjusting initial concentration of reactants and different reducing agents. The Cu2O nano/microstructures exhibited excellent photoluminescence propertiesThe obtained products were characterized by X-ray powder diffractometer (XRD) and scanning electron microscopy (SEM). the possible mechanism was discussed.
