چکیده

Laser evaporation of MoS(2) nanoflakes gives negatively charged magic number clusters of compositions Mo(13)S(25) and Mo(13)S(28), which are shown to have closed-cage structures. The clusters are stable and do not show fragmentation in the post-source decay analysis even at the highest laser powers. Computations suggest that Mo(13)S(25) has a central cavity with a diameter of 4.5 A. The nanosheets of MoS(2) could curl upon laser irradiation, explaining the cluster formation.

NH3 sensors based on novel TiO2/MoS2 nanocomposites: Insights from density functional theory calculations

Density functional theory calculations were performed to investigate the interactions of NH3 molecules with TiO2/MoS2 nanocomposites in order to completely exploit the adsorption properties of these nanocomposites. Given the need to further comprehend the behavior of the NH3 molecules oriented between the TiO2 nanoparticle and MoS2 monolayer, we have geometrically optimized the complex systems ...

Modification of Deposited, Size-Selected MoS2 Nanoclusters by Sulphur Addition: An Aberration-Corrected STEM Study

Molybdenum disulphide (MoS2) is an earth-abundant material which has several industrial applications and is considered a candidate for platinum replacement in electrochemistry. Size-selected MoS2 nanoclusters were synthesised in the gas phase using a magnetron sputtering, gas condensation cluster beam source with a lateral time-of-flight mass selector. Most of the deposited MoS2 nanoclusters, a...

Closed-cage clusters in the gaseous and condensed phases derived from sonochemically synthesized MoS2 nanoflakes.

The Mo(13) clusters we previously reported were derived from MoS(2) flakes prepared from bulk MoS(2), although the nature of the precursor species was not fully understood. The existence of the clusters in the condensed phase was a question. Here we report the preparation of MoS(2) nanoflakes from elemental precursors using the sonochemical method and study the gas-phase clusters derived from t...
