Synthesis of Cu(OH)₂ Nanowires at Aqueous−Organic Interfaces

Abstract

Cu(OH)2 nanowires have been successfully synthesized at the organic−aqueous interface by the interaction of the copper−bis(2-ethylhexyl) phosphate complex in the organic layer with NaOH in aqueous layer. The nanowires have an average length of 4 μm and are several nanometers in width. CuO nanowires and short wiskers are conveniently prepared through dehydration of Cu(OH)2 at high concentrations of NaOH under ambient conditions. Transmission electron microscopy and X-ray diffraction techniques have been used to characterize the microstructures and morphologies of the nanowire materials.
