Single-crystalline scroll-type nanotube arrays of copper hydroxide synthesized at room temperature

A novel nanolayer-rolled tubular structure of Cu(OH)(2) has been grown in solution at ambient temperature and pressure. Significantly, the Cu(OH)(2) nanotubes are phase-pure single crystallites and are arrayed uniformly on copper substrates (see Figure). The reaction conditions for the fabrication of the nanotube arrays are examined and possible growth mechanisms are discussed.
