Hydrothermal Synthesis of AlOOH Hierarchical Microstructure

在表面活性剂PVP和CTAB的辅助下采用简单的水热法,成功地合成了不同形貌的AlOOH.同时,通过XRD,TEM,HRTEM,SAED等一系列手段对其进行探讨和研究,结果表明:反应时间和表面活性剂的浓度对样品的形貌起到了至关重要的作用.此外,实验研究发现表面活性剂PVP和CTAB在反应中起到不可替代的作用.目前还没有任何文章报道有关在水热条件下采用简单的方法合成不同形貌的AlOOH.

Different of AlOOH hierarchical microstructure have been successfully synthesized with the assistance of Polyvinylpyrrolidone（PVP） and hexadecyl trimethyl ammonium bromide（CTAB） by a facile hydrothermal method.The as-synthesized samples were characterized by X-ray diffraction（XRD）、 transmission electron microscopy（TEM）、 high-resolution transmission electron microscopy（HRTEM） and selected area electron diffraction（SAED）.The results show that the reaction time and the concentration of the surfactant play an important role for the morphology of the sample.In addition,the experiment research shows that PVP and CTAB play an irreplaceable role in the reaction.To the best of our knowledge,there have been no any report on the one-pot synthesis of different of AlOOH hierarchical microstructure in the hydrothermal system.
