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, I n0.5Hg0.5, Sn0.15Ga0.85, and NaxHg), The intercalation process was mon itored 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 selectivel y, The final products were found to be comparable to those obtained by high temperature synthesis, In the case of 1T-TaS2 a soft chemistry i nduced Ta-coordination change from octahedral to trigonal-prismatic wa s observed.
