Orthorhombic Cu(OH)2nanowire bundles were prepared at low cost by simply pouring NaOH into a CuSO4and H2O2mixing solution at room temperature. The Cu(OH)2nanowire bundles were assembled by the directional arrangement of polycrystalline nanowires, consisting of orthorhombic Cu(OH)2nanocrystallites. The morphology of Cu(OH)2is significantly influenced by the H2O2concentration. Higher H2O2concentrations result in longer Cu(OH)2bundles. The results of time-dependent experiments indicate that H2O2promotes the Cu(OH)2recrystallization and directional growth. CuO nanostructure is obtained by thermal dehydration of the as-prepared Cu(OH)2nanowire bundles in the solid state, which preserves the morphology of the original Cu(OH)2bundles.
