Outline of Final Research Achievements

We investigated the mechanism why our MOF selectively separates metals such as strontium. We made the strontium adsorbed MOF crystal and revealed structure. As a result the structure was completely different from the MOF structure before adsorption. Although MOF has been extensively studied, it has not been reported so far that such a significant structural change occurs during metal adsorption, and this research makes use of the characteristics of MOF which is easy to make crystal and analyze structure. This study can clarify the adsorption behavior which has not clarified so far and the unusual structural change of MOF.
