Synthesis and characterization of CuO nanowhiskers by a novel one-step, solid-state reaction in the presence of a nonionic surfactant

Abstract A novel and simple one-step, solid-state reaction in the presence of a nonionic surfactant, PEG 400, has been developed to synthesize CuO nanowhiskers with diameters of approximately 2–10 nm and lengths of more than 100 nm. The CuO nanowhiskers were characterized by XRD, TEM, HRTEM and XPS.
