At the previous meeting, we showed the simple and rapid synthesis of alkali metal- and alkaline earth metal-intercalated GICs by using Na as a catalyst. In the present study, the Na-catalysed method was applied to the synthesis of lanthanide (Ln)-intercalated GICs (LnC₆). The results demonstrate that bulk samples of LnC₆ (Ln = Sm, Eu, Yb) can be rapidly synthesized in high yield. This study demonstrates the versatility of the Na-catalyzed method and lays the foundation for the mass production of LnC₆.
