General description

Molybdenum disulfide is a two dimensional layered material. Monolayers of transition metal dichalcogenides (TMDs)exhibit photoconductivity. The layers of the TMD can be mechanically or chemicaly exfoliated to form nanosheets.
We are committed to bringing you Greener Alternative Products, which belongs to one of the four categories of greener alternatives. This enabling product has been enhanced for energy efficiency. Click here for more information.

Application

Acidic solution of MoS2 particles was used to catalyze hydrogen evolution at a water 1,2-dichloroethane interface. MoS2 was dispersed in N-methyl-pyrrolidone to form exfoliated MoS2 flakes of various sizes. MoS2 ink was used for inkjet printer. MoS2 may find potential applications in electronics and optoelectronics.
