Three-Dimensional Hierarchical Structures of ZnO Nanorods as a Structure Adsorbent for Water Treatment

引用

Journal of Materials Science & Technology 2017年第8期33卷 864-868页

作者： Zhendong Li Yingjie Huang Xingfu Wang Dan Wang Xinfu Wang Fusheng Han Key Laboratory of Materials Physics Institute of Solid State PhysicsChinese Academy of SciencesHefei 230031China

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.
