Figure 2: Characterization of intercalated and exfoliated MoS2.
From: High yield exfoliation of two-dimensional chalcogenides using sodium naphthalenide
(a) XRD pattern and schematic of pristine MoS2, Na-intercalated MoS2, after exposure of Na-intercalated MoS2 to the ambient for 3 days, exfoliated-and-restacked naphthalene-intercalated MoS2. (b) Li-, Na- and K-intercalated MoS2, after exposure of intercalated sample to the ambient for 3 days. (c) Li-, Na- and K-exfoliated MoS2 without any annealing. (d) Solid-state 7Li NMR spectra of LixMoS2 and Lix(H2O)yMoS2, (e) Solid-state 23Na NMR spectra of NaxMoS2 and Nax(H2O)yMoS2.
