一种制备多壳层空心结构金属有机框架材料的方法
摘要：
本发明公开了一种制备多壳层空心结构金属有机框架材料的方法。该方法首先制备金属有机框架材料(MOF)，然后分散到质子溶剂中进行刻蚀，得到单层空心的MOF；以MOF为晶种，外延生长得到MOF@MOF，然后分散到质子溶剂中进行刻蚀，得到双层空心的MOF；重复外延生长步骤得到多壳层MOF，最后经刻蚀得到多壳层空心结构MOF。该方法简单易行，条件温和，安全性高，可以得到多壳层空心MOF，具有广阔的应用前景。
摘要（英）：

The invention discloses a method for preparing a multi-shell hollow structure metal organic framework material. The method comprises: preparing a metal organic framework material (MOF), dispersing in a protic solvent, and etching to obtain monolayer hollow MOF; epitaxially growing by using the MOF as a crystal seed to obtain MOF@MOF, dispersing in a protic solvent, and etching to obtain double-layer hollow MOF; and repeatedly performing epitaxial growth to obtain multi-shell MOF, and finally etching to obtain the multi-shell hollow structure MOF. According to the present invention, the method has advantages of simpleness, easy performing, mild condition, high safety and broad application prospect, and can obtain the multi-shell hollow MOF.
