Thin layer molybdenum disulfide dispersion

Product Overview
This product is a ready-to-use dispersion of thin-layer molybdenum disulfide (MoS₂), a two-dimensional transition metal dichalcogenide with a graphene-like layered structure. While MoS₂ exists in 1T, 2H, and 3R crystal phases, the bulk material is predominantly the stable 2H phase with a hexagonal sandwich structure. We synthesize this material via a lithium intercalation method: n-butyllithium inserts lithium ions between the MoS₂ layers, forming an intercalation compound that expands in solvent and is then exfoliated via ultrasonication. The resulting nanosheets feature a 1T-2H mixed-phase structure, with approximately 60% 1T phase content (batch-dependent).
