Single‐Crystalline Scroll‐Type Nanotube Arrays of Copper Hydroxide Synthesized at Room Temperature

Abstract

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.
