Controlled Exfoliation of MoS2 Crystals into Trilayer Nanosheets.
The controlled exfoliation of transition metal dichalcogenides (TMDs) into pristine single- or few-layer nanosheets remains a significant barrier to fundamental studies and device applications of TMDs. Here we report a novel strategy for exfoliating crystalline MoS2 into suspensions of nanosheets with retention of the semiconducting 2H phase. The controlled reaction of MoS2 with substoichiometr...
متن کاملSpontaneous exfoliation and tailoring of MoS2 in mixed solvents.
Spontaneous exfoliation of MoS2 is achieved in H2O2-NMP mixed solvents with a yield of over 60 wt%, operated under mild conditions. H2O2-prompted sheet-tailoring effect induces a size evolution of MoS2 nanosheets from micro-scale to nano-scale. Furthermore, the concurrent dissolution also affords an approach to introduce structural defects in the nanosheets.

Remarkable Activity and Stability of Photocatalytic Hydrogen Production over Dye-Sensitized Single Molecular Layer MoS2 Ensemble Experimental Preparation of S-MoS2 Single-layer MoS2 was synthesized by the exfoliation of MoS2 with lithium intercalation[1]. The starting material used in the reported studies was bulk MoS2 powder from Sigma Aldrich. 500 mg of the black MoS2 powder was first soaked ...
متن کاملUnderstanding graphene production by ionic surfactant exfoliation: A molecular dynamics simulation study
We have simulated sodium dodecyl sulfate (SDS) surfactant/waterþ bilayer graphene mixture system to investigate two mechanisms of graphene exfoliation: changing the interlayer distance and sliding away the relative distance. By calculating the total energy as a function of the interlayer (sliding-away) distance at different surface-coverage concentrations of SDS surfactant (SDS concentrations),...
متن کاملInvestigation of Melting by Molecular Dynamics Simulation
The melting of a 64 ion microcrystal of KCI was studied by means of a molecular dynamics computer simulation. We used a central pair interaction with an inverse power law repulsion. The thermodynamics, kinetic and structural properties such as melting temperature, latent heat, mean square displacement, diffusion constant, radial distribution function and bond angle distribution are calculated. ...
