Abstract
We report a low-temperature sonochemical method for the synthesis of CuO nanostructure. CuO nanowires 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 °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 nanoparticles (SW-CTAB1) have an ideal one-dimensional CuO nanostructure with a high Brunauer-Emmett-Teller surface area of 62.15 m2 g−1. Furthermore, the SW-CTAB1 electrodes exhibited a good lithium activity.
