1D Cu(OH)(2) nanowires with a high yield were successfully synthesized under ultrasound irradiation of 40 kHz ultrasonic waves at the output power of 100% at 70 degrees C for 5 min without the assistance of any surfactant, employing CuCl2 center dot 2H(2)O and NaOH as the initial materials. X-ray diffraction (XRD) analyses and field emission scanning electron microscopy (SEM) observations of the products showed that 1D Cu(OH)(2) nanowires could be completely converted into 3D CuO microstructures after the system had been continuously irradiated by ultrasonic waves for 45 min. A time-dependent. shape evolution was investigated. Furthermore, research indicated that Cu(OH)(2) nanowires and CuO microstructures could promote electron transfer between the glassy-carbon electrode and organic small molecules Such as L-ascorbic acid and catechol, which is rarely reported in previous literature.
