Molybdenum disulfide (MoS 2 ) presents fascinating properties for next-generation applications in diverse fields. However, fully exploiting the best properties of MoS 2 in largescale practical applications still remains a challenge due to lack of proper processing methods. Solution-based processing can be a promising route for scalable production of MoS 2 nanosheets, but the resulting assembled film possesses an enormous number of interfaces that significantly compromise the intrinsic electrical properties. Herein, we demonstrate the solution processing of MoS 2 and subsequent precursor-assisted chemical welding to form defective MoS 2-x at the nanosheet interfaces. The formation of defective MoS 2-x significantly reduces the electrical contact resistances, and thus the chemically welded MoS 2 film exhibits more than 2 orders of magnitude improved electrical conductivity. Furthermore, the chemical welding provides MoS 2-x interface induced additional defect originated functionalities for diverse applications such as broadband photodetection over the near-infrared range and improved electrocatalytic activity for hydrogen evolution reactions. Overall, this precursor-assisted chemical welding strategy can be a facile route to produce high-quality MoS 2 films with low-quality defective MoS 2-x at the interfaces having multifunctionalities in electronics, optoelectronics, and electrocatalysis.

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.

Both p - n and n - p heterojunctions of ZnO-MoS2 have been fabricated in order to understand the performance of electron and hole transport properties in solar cells and a self-powered photodetector system. Atomically thin 2-dimensional (2D) MoS2 was prepared by using a spin coating method with controlled process times, whereas ZnO nanowires were prepared by using a plasma sputtering deposition technique. The nanoscale morphologies, composites, and photoelectric properties of nanocomposites were examined using scanning electron microscopy, energy-dispersive X-ray spectroscopy, and micro-Raman scattering spectroscopy, respectively. 2D heteronanostructures have exhibited an enhanced performance as compared to single-material-based prototypes. In photovoltaic mode, n - p heterojunction of the ZnO-MoS2-based prototype appears to have much better photoelectric conversion efficiency than that in the case with p - n junction, indicating highly effective hole transport properties of 2D MoS2 materials. Both band broadening and band shift were observed. Furthermore, the bias, annealing, and synergistic effects on the generated photocurrents and the response times were evaluated. The newly designed prototype exhibits exceptional properties: a broadband spectral response, a high signal-to-noise ratio, and excellent stability.
