文摘
Copper microstructures assembled with nanowalls have been synthesized in aqueous solution at 200 
C for 24 h.Two different novel morphologies, microstructures with net and radial shapes, were obtained by controlling the concentration of thestarting materials. The samples were characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM), field-emissionscanning electron microscopy (FE-SEM), and transmission electron microscopy (TEM) technologies. The formation mechanism ofthe morphology control over the copper microstructures was investigated; the addition of NaOH in aqueous solution and the choiceof NaH2PO2·H2O as the reducing agent were found to be important for the final generation of copper microstructures.
