Flower-shaped CuO with hierarchical microstructures was successfully synthesized through an ultrasound-assisted aqueous chemical method. The comparative experiment results show that the phase and morphology of as-obtained products are greatly affected by the volume of ammonia and the time for keeping ultrasonic irradiation, respectively. The prepared CuO microflowers assembled by nanosheets with needle-like tips exhibit a much higher activity than the commercial CuO for degrading Rhodamine B. Additionally, the photocatalytic performance of as-prepared hierarchical CuO microflowers was also evaluated through the degradation of Methylene blue and Methyl orange under the same conditions.
