Controllable synthesis of CuO nanowires and Cu_2O crystals with shape evolution via γ-irradiation

摘要

Copper oxide nanowires and cuprous oxide crystals had been synthesized through γ-irradiating aqueous CuCl_2-NaOH-sodium dodecyl sulfate (SDS)-isopropyl alcohol solutions under ambient conditions. The product composition could be changed by modulating the amount of base, NaOH. The morphology of the products could be accurately controlled by altering the amounts of SDS and isopropyl alcohol. A possible formation mechanism was also proposed.
