Abstract
ZnO nanorod arrays (NRs) are successfully synthesized on CuO thin film by hydrothermal method. The result of scanning electron microscopy demonstrates that the ZnO NRs produce great changes on morphology after deposited on CuO thin film. The current–voltage measurement of ZnO NRs/CuO film heterostructures show an evident rectifying behavior. Furthermore, the photocatalytic activity is investigated by degradation of methyl orange dye. It is found that compared with ZnO NRs, ZnO NRs/CuO film heterostructures display a better photocatalytic activity.
