Novel single layer materials of the form MX2, where MX2 is a layer-type dichalcogenide such as MoS2, TaS2, WS2, or the like, exfoliated by intercalation of an alkali metal, and immersion in water, are disclosed. MoS2 has been exfoliated into monolayers by intercalation with lithium followed by reaction with water. X-ray diffraction analysis demonstrates that the exfoliated MoS2 in suspension is in the form of one-molecule-thick sheets. X-ray patterns from dried and re-stacked films of exfoliated MoS2 indicate that the layers are randomly stacked. By adsorbing monolayers or precipitating clusters of various species such as compounds of Co, Ni Pb, Cd, Al, Ce, In and Zn, on MoS2 while the …
