Abstract

Molybdenum disulfide (MoS2), a promising two-dimensional transition-metal dichalcogenide, presents a challenge in the tuning of its optoelectronic and chemical properties. Herein, we demonstrate an efficient route to alter the crystalline structure of MoS2by chemical exfoliation. Using NaK metal alloys, exfoliated and covalently functionalized MoS2derivatives were obtained with a high metallic (1T) phase ratio, up to 94.5%. Consequently, exfoliated MoS2showed a significant surface-enhanced Raman scattering activity toward rhodamine 6G (R6G) and crystal violet, with low detection limits. The versatility of this approach allows the covalent functionalization of MoS2without relying on edge or basal-plane defects of the structure and preserving the high-ratio 1T phase.

Abstract

Wet chemistry in organic solventshas proven highly efficient for the preparation of several types ofmetallic, metal-oxide, and semiconductor nanostructures. This ShortReview focuses on the use of oleylamine (OAm) as a versatile reagentfor the synthesis of various nanoparticle systems. We describe theability of OAm to act as a surfactant, solvent, and reducing agent,as a function of other synthesis parameters. We also discuss the specificrole of OAm either alone or in combination with other reactants, toform nanostructures using a variety of organic or inorganic compoundsas precursors. In certain cases OAm can form complex compounds withthe metal ions of the corresponding precursor, leading to metastablecompounds that can act as secondary precursors and thus be decomposedin a controlled way to yield nanoparticles. We also point out thatOAm-stabilized particles can often be dispersed in different organicsolvents yielding solutions with enhanced colloidal stability overlong times and the potential to find applications in a number of differentfields.
