Large-scale production of 2H-MoS2 sheets by ultrasonication.

(a) An Im−-assisted exfoliated 2H-MoS2 suspension on the liter-scale made by ultrasonic exfoliation. (b) The as-prepared 2H-MoS2 suspension after standing for more than a year. (c) The PL spectra of Im− (black line), Im−/2H-MoS2 without sonication (red dotted line) and Im−/2H-MoS2 with sonication (blue dashed line). (d) Zeta potential distributions of the Im−‒assisted 2H-MoS2 suspension.
