Abstract pn-Type Cu2O/CdS nanowires arrays were successfully fabricated in the porous anodic aluminum oxide (AAO) template by an electrodeposition method. The surface morphology of Cu2O/CdS nanowires was characterized by scanning electron microscopy (SEM) and transmission electron microscopy (TEM). Structural analysis of Cu2O/CdS nanowires was discussed by X-ray diffraction (XRD) analysis. The difference of open circuit potential and optical absorption spectra were measured to research the properties of Cu2O/CdS nanowires. The diameter of the nanowires is about 100 nm, which is the same as the pore diameter of AAO template. X-ray diffraction analysis identifies a cubic structure of the Cu2O and mixed crystal structures of cubic and hexagonal of the CdS. Light response property of Cu2O/CdS nanowires is enhanced. Meanwhile, Cu2O/CdS nanowires arrays exhibit a good activity for photodegrading Rhodamine B under a Xe lamp irradiation and the degradation efficiency is up to 66.02% after the degradation for 7 h.
