Abstract: This thesis reported the synthesis of metallic Cu, cuprous oxide (Cu2O), and cupric oxide (CuO) with different nanostructures. We at first developed several wet-chemical methods for synthesis of one-dimensional CuO nanostructures. Secondly, we investigated the synthesis of Cu2O nanostructures using acidic and basic conditions respectively. In the acidic condition, a full range of novel multipod frameworks of Cu2O microcrystals has been prepared. In the basic condition, the N,N-dimethylformamide (DMF) was used as solvent. With the increase of water in the Cu2+ (0.005-0.01 M) DMF solution, the morphology of formed Cu2O nanoparticles changes from hollow spheres to hollow cubes and then to large cubes. Finally, we synthesized highly regulated ultralong copper nanowires (more than 40 um) under mild conditions, and the growth direction of these wires is along the <110>.
