研究了MIL-53 (Al)在室温至100℃不同pH水溶液中的结构稳定性。实验结果表明，MIL-53 (Al) 在中性和酸性溶液中稳定且高度耐水解。它可以保持其结晶度和永久孔隙率而不会发生结构塌陷。 MIL-53 (Al) 对水溶液的良好结构稳定性在 MOF 中非常罕见。浸泡后的骨架的氮吸附显示出典型的 I 型等温线。在碱性水溶液中，MIL-53 (Al) 发生结构转变。版权所有 (C) 2013，Hydrogen Energy Publications, LLC。由爱思唯尔有限公司出版。保留所有权利。
The structural stability of MIL-53 (Al) in different pH aqueous solutions from room temperature to 100 degrees C has been investigated. Experimental results show MIL-53 (Al) is stable and highly resistant to hydrolysis in neutral and acidic solutions. It can retain its crystallinity and permanent porosity without structural collapse. The good structure stability of MIL-53 (Al) to aqueous solutions is quite unusual among the MOFs. The nitrogen adsorption for the soaked frameworks show a typical type I isotherm. In basic aqueous solution, MIL-53 (Al) undergoes structure transformation. Copyright (C) 2013, Hydrogen Energy Publications, LLC. Published by Elsevier Ltd. All rights reserved.
