A controllable synthetic route to Cu, Cu2O, and CuO nanotubes and nanorods

Reducing Cu(OH)(4)(2-) with hydrazine hydrate and glucose in the presence of a structure-directing surfactant at room temperature gave Cu and Cu2O nanotubes/nanorods, respectively, whereas facile hydrothermal treatment of Cu(OH)(4)(2-) precursor resulted in CuO nanotubes/nanorods.
