Three-dimensional(3D) ZnO nanorods with good adsorption property was successfully fabricated via a facile hydrothermal method, and characterized by scanning electron microscopy(SEM), X-ray diffraction(XRD), Energy Dispersive X-ray spectrometer(EDX) and a UV-vis spectrophotometer. It was found that the ZnO nanorods with a diameter of 0.5 μm and the length of 10 μm were firmly grown on the struts of the open-cell aluminum foams, and the 3D hierarchical structured adsorbent Zn O nanorods/Al foam(r-ZnO/AF) exhibits a higher adsorption capacity for Brilliant Blue R(BBR) in aqueous solutions, more stable sorption regenerable behavior and solid–liquid separability in contrast to the corresponding n-ZnO powder sample. The kinetics of the adsorption process was also discussed.
