Facile synthesis of MoS2 nanosheet-silver nanoparticles composite for surface enhanced Raman scattering and electrochemical activity

A general one-step approach for in situ decoration of MoS2 nanosheets with inorganic nanoparticles

“…Recent studies show that the MoS 2 nanosheet can be applied effectively in catalysis, optoelectronic devices, and biosensors. [17][18][19][20][21][22][23][24][25] This is not due to the unimportance of this issue, but likely due to the extreme difficulty in the controllable and scalable fabrication of MoS 2 -INP nanohybrids. [17][18][19][20][21][22] From the perspective of materials design, the decoration of INPs not only suppresses the agglomeration and restacking of MoS 2 nanosheets that may result in the loss of the unique layer-dependent properties but also endows MoS 2 nanosheets with new physical and chemical properties.…”

Nanocomposites of Two-Dimensional Molybdenum and Tungsten Dichalcogenides with Metal Particles: Preparation and Prospects for Application

“…An exception to this behavior is found for the product of the reaction in N-methylpyrrolidone, a nonaqueous solvent, involving multilayered MoS 2 sheets, in which round or oval-shaped crystalline silver NP have high size dispersion (20-80 nm) and are partially agglomerated in pyramidal formations with diameter of several hundred nanometers [105].…”

“…Thus, the Ag@MoS 2 nanocomposite may be used for detection of 2-mercaptobenzimidazole [105] or 1-phenyl-5-mercaptotetrazole [122] as test molecules capable of coordinating with silver through their thiol groups. These results suggested that organic molecules indeed bind with metal domains; 2-mercaptobenzimidazole has perpendicular orientation relative to the surface of the silver NP.…”

Tailored performance of layered transition metal dichalcogenides via integration with low dimensional nanostructures

“…Many reports have demonstrated TMDs-based sensors, when integrated with noble metal or metal oxide semiconductors, exhibiting an enhanced performance compared with individual component. [166][167][168] biosensor that could detect glucose in a concentration range from 10 to 300 mM with a detection limit of 2.8 mM.…”
