- Abstract
- We report a low-temperature sonochemical method for the synthesis of CuO nanostructure. CuO na-nowires and ellipsoidal CuO nanostructures were fabricated using 20 kHz ultrasonic irradiation. The ultrasonic irradiation led to the efficient precipitation of crystalline CuO nanoparticles at 10 degrees C without additional dehydration or heat treatment. The formation mechanism of the CuO nanostructures was investigated by X-ray diffraction, field emission scanning electron microscopy, and transmission electron microscopy with respect to the exposure time and amount of surfactant. The optimized CuO nano particles (SW-CTAB1) have an ideal one-dimensional CuO nanostructure with a high Brunauer-EmmettTeller surface area of 62.15 m(2) g(-1). Furthermore, the SW-CTAB1 electrodes exhibited a good lithium activity. (C) 2016 Elsevier Ltd and Techna Group S.r.l. All rights reserved.
