a Solution pH changes upon the ultrasonication of Li intercalated MoS2 in oxygenated (Ox), deoxygenated (D.Ox), and deionized (D.I) water. Solution pH change upon hydration of Li intercalated WSe2 in oxygenated water is also provided. b Schematic presentation of energetically favored removal of SO2 from MoS2 surface. c XPS analyses of Mo3d orbits of MoS2 sheets of pure 2H phase and 2H:1 T′ combined phase and MoS2 NRs prepared in oxygenated water. d–f HAADF and Elemental mapping (W, and Se) of partially unzipped WSe2 layered sheet displaying Se as a byproduct and line defects on the basal plane. Scale bars, 0.2 µm.
