Graphene-like MoS2 prepared by a novel intercalation-detonation method

Graphene-like MoS2 has attracted significant interest because of its unique electronic, optical and catalytic properties with two-dimensional lamellar structure. A novel intercalation-detonation method was used to prepare monolayer and multilayer graphene-like MoS2. MoS2 was first completely intercalated by abundant oxygen-containing functional groups bonded to the sulfur atom layer in basal planes of the MoS2 structure, increasing the layer spacing and decreasing the Van-der-Waals' force between the layers. Then, the intercalated MoS2 was rapid exfoliated by high energy of detonation. Characterization results indicate that the graphene-like MoS2 was successfully prepared by the explosion method. This type of processing is simple, highly efficient and generates fewer impurities.
