在50 °C的碱性体系中，用葡萄糖还原Cu（II）制备了不同形貌的Cu 2 O颗粒。采用X射线衍射（XRD）、扫描电镜（SEM）和透射电镜（TEM）对产物进行了表征。结果表明，随着NaOH浓度的变化，Cu 2 O颗粒的形状发生了变化。Cu_2O颗粒形貌的不同是由于OH ~-离子在Cu_2O颗粒上的吸附，引起了Cu_2O颗粒生长方式的变化，进而影响了Cu_2O颗粒的形貌。
Cu2O particles with different shapes were prepared via reducing Cu(II) in alkaline system by glucose at 50 °C. The products were characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM) and transmission electron microscopy (TEM). It is found that the shape of Cu2O particles changes with the change of concentration of NaOH. The different shapes of Cu2O particles are due to the absorption of OH-ions on Cu2O particles, which arise the variety of growth mode of Cu2O, and then influence the morphology of Cu2O particles.
