Molybdenum disulfide quantum dots: synthesis and applications

Abstract

Recently, two-dimensional (2D) layered transition metal dichalcogenides (TMDs) have received a notable amount of interest due to their fascinating properties and versatile potential applications. One such material is molybdenum disulfide (MoS₂), which has unique, superior functional properties including high current-carrying capacity and large carrier mobility which have drawn interest in many emerging fields. In particular, MoS₂ quantum dots (QDs) are being investigated for various applications such as electrocatalytic activity in hydrogen evolution reactions, sensing and bioimaging. In this review, we will take 2D TMD MoS₂ QDs as a typical example and discuss the latest research advancement with emphasis on synthesis and applications.
