ZnO nanorod arrays (NAs) were prepared by a simple two‐step process on the Ag rods. The X‐ray diffraction and HRTEM characterizations indicated that ZnO nanorods were hexagonal wurtzite single crystalline structure. Photoelectrocatalytic performances of Ag rods with ZnO NAs (ZnO NAs/Ag rods) were studied systematically for the removal of rhodamine B (RhB). Under the optimal condition, the photoelectrocatalytic efficiency was nearly twice the photocatalytic efficiency, which can be attributed to the more efficient separation of photo‐generated carriers. Our results show that ZnO NAs/Ag rods should be a promising photoelectrode for photoelectrocatalysis progress.
