Outline of Final Research Achievements

Layered compounds including layered nitrides, MAX-phase derived compounds, and oxide-based layered metalates, have attractive much attention as efficient ion exchangers. In this study, we prepared various adsorbents including MXene and titanate-based crystals and applied to selective ion exchange reactions. The cation exchange capacities of MXene-based adsorbents were 0.1-0.3 mmol/g, and the selective adsorption properties were not obserbed. We found that KTiNbO5 and H2TiO3 are selective adsorbents for strontium and lithium ions, respectively.
