- Abstract
- Nanostructured copper compounds were grown by electrochemical anodization of copper foil in aqueous NaOH under varying conditions including electrolyte concentration, reaction temperature, current density, and reaction time. Their morphology and atomic composition were investigated by using SEM, TEM, XRD, EDS and XPS. At the conditions ([NaOH] = 1 M, 20 degrees C, 2 mA cm(-2)), wire-like orthorhombic Cu(OH)(2)nanobundles with an average width of 100 - 300 nm and length of 10 mu m were synthesized with the preferential [100] growth direction. Furthermore, when the concentration decreased to 0.5 M NaOH, the ID nanobundle structure became narrower and longer without any change in compositions or crystalline structure. Side reaction pathways appeared to compete with the ID nanostructure ormation channels: the formation of CuO nanoleaves at 50 degrees C via the sequential dehydration of Cu(OH)(2), CuO/Cu2O aggregates in 4 M NaOH, and Cu2P nanoparticles and CuO nanosheets at lower current density.
