Ambient-Temperature Intercalation of Na and in into TaS2
We report on ambient temperature intercalation of Na and In into TaS2 (2H and 1T) using liquid metal eutectics and amalgams (In0.17Ga0.83, In0.5Hg0.5, Sn0.15Ga0.85, and NaxHg), The intercalation process was monitored in situ by measuring the Ta-181 nuclear-quadrupole-interaction (NQI) via time differential perturbed angular correlation (TDPAC). At ambient temperature, a single metal species is intercalated selectively, The final products were found to be comparable to those obtained by high temperature synthesis, In the case of 1T-TaS2 a soft chemistry induced Ta-coordination change from octahedral to trigonal-prismatic was observed.
