Herein, a facile and cost-effective strategy for hydrothermal synthesis of three-dimensional (3D) MoS2 with adequate active edge sites and advanced hydrogen evolution reaction (HER) performance using polypyrrole (PPy) as template is reported. The MoS2 is first thermally nucleated using hexaammonium heptamolybdate tetrahydrate (NH4)6Mo7O24·4H2O and thiourea as precursor in the presence of PPy, a...

Bulk MoS2, a prototypical transition metal chalcogenide material, is an indirect band gap semiconductor with negligible photoluminescence. In this study, we have developed, for the first time, a simple and low-cost synthetic strategy to prepare boron- and nitrogen-doped MoS2 (B,N-MoS2) nanosheets. Through boron and nitrogen doping, the band gap of MoS2 increases from 1.20 eV to 1.61 eV, and the...

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 ...

MoS2 nanosheet, a new two-dimensional transition metal dichalcogenides nanomaterial, has attracted significant attentions lately due to many potential promising biomedical applications. Meanwhile, there is also a growing concern on its biocompatibility, with little known on its interactions with various biomolecules such as proteins. In this study, we use all-atom molecular dynamics simulations...

In this work, we report on a simple and scalable process to synthesize the core-shell nanostructure of MoS2@N-doped carbon nanosheets (MoS2@C), in which polydopamine is coated on the MoS2 surface and is then carbonized. An intensive investigation using transmission electron microscopy and Raman spectroscopy reveals that the as-synthesized MoS2@C possesses a nanoscopic and ultrathin layer of MoS...

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 ...
