Abstract
The spherical shaped cuprous oxide (Cu2O) cluster was synthesized on metal aluminum by the galvanostatic method. The adsorption of hydroxide ion from dissolved oxygen and nitrate ion increased the local surface pH and resulted in the formation of aluminum (hydro) oxide. Irregular dissolution of aluminum (hydro) oxide due to non-uniform pH distribution was observed. Then, the spherical Cu2O cluster was deposited on conducting aluminum surface. This result was clearly characterized by means of scanning electron microscope, energydispersive X-ray analysis, and X-ray diffraction measurement.
