摘要

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 ZnO 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.
