Effect of OH⁻ on morphology of Cu₂O particles prepared through reduction of Cu(II) by glucose

Abstract

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.
