Progress and development on the synthesis and application of two-dimensional molybdenum disulphide

Abstract

Two-dimensional (2D) molybdenum disulphide (MoS2) stands out with its unique tunable bandgap and optoelectronic properties, making it a prime focus in transition metal dichalcogenides (TMDs) research. It has wide-ranging applications in energy storage, electronics, optoelectronics and high-performance sensing materials. Synthesis methods fall into top-down (chemical, mechanical and liquid-phase exfoliation) and bottom-up (physical vapour deposition, chemical layer deposition, atomic layer deposition and solvothermal/hydrothermal) categories. Choosing the right synthesis method is pivotal as it significantly impacts the material's properties and application potential. 2D MoS2, owing to its natural abundance, adaptability, adjustable bandgap and high surface-to-volume ratio, finds utility in various domains like energy storage, catalysis, composite and sensors. This review delves into recent progress, challenges and future prospects in 2D MoS2 synthesis and applications.
