CuO nanoplates (NPs) have been prepared on ZnO nanorods (NRs) to form heterostructure by a simple photodeposition method at room temperature. The morphology, composition, and structure of the as‐prepared CuO NPs/ZnO NRs heterostructure were analyzed by SEM, TEM, XPS, and XRD. UV/Vis absorption spectrum indicates that the CuO NPs/ZnO NRs heterostructure exhibits a strong absorption in both the UV and visible light region. Photocurrent response results and the photoluminescence spectrum confirm that the CuO NPs/ZnO NRs heterostructure could promote the separation of photogenerated carriers. The photocatalytic ability of the as‐prepared samples was evaluated by degrading methyl orange. Moreover, the possible growth and photocatalytic mechanisms of the CuO NPs/ZnO NRs heterostructure were discussed.
