Room-Temperature Production of Nanocrystalline Molybdenum Disulfide (MoS) at the Liquid-Liquid Interface.

Scalable synthesis of 2D materials is a prerequisite for their commercial exploitation. Here, a novel method of producing nanocrystalline molybdenum disulfide (MoS) at the liquid-liquid interface is demonstrated by decomposing a molecular precursor (tetrakis(diethyldithiocarbamato) molybdenum(IV)) in an organic solvent. The decomposition occurs over a few hours at room temperature without stirring or the addition of any surfactants, producing MoS which can be isolated onto substrates of choice.
