Novel tomato‐shaped copper oxide crystals has been prepared by a simple hydrothermal method with the presence of Zn 2+ ion. The ultrasonic pretreatment has proved to be the key factor during the synthesis process. Scanning electron microscope, energy dispersive X‐ray spectrometry and powder X‐ray diffraction were used to characterize the microstructure and morphology of the as‐prepared products. The obtained tomato‐shaped CuO particles were constructed by nanorods with the diameter of about 20 nm. The possible growth mechanism was proposed based on the experimental results.
