| Cu2O/Cu crystalline particles were synthesized via solvothermal reaction using dodecyl sulfate sodium as surfactant and D-glucose as reducing agent at 140°C for 4h. The products were characterized by means of transmission electron microscopy (TEM) and X-ray diffraction (XRD). The different morphologies of Cu2O/Cu crystals such as spherical and cubic can be obtained simply by adjusting the composition of the reaction system. For example, if small amounts of water was added in a mixture of Cu(NO3)2 and ethanol, the cubic morphology crystals could be formed. Moreover the ratio of water/ ethanol played a crucial role in fine tuning the structure and size of as-prepared Cu2O/Cu nanocrystals.In this paper, the formation mechanism of obtained cubic and spherical Cu2O/Cu crystalline particles is discussed. |
