Abstract : Nanotechnology has attracted considerable interest due to its ability to manipulate matter at the atomic and molecular levels.This comprehensive review focuses on nanomaterials, specifically emphasizing metal sulphides, elucidating their distinctive properties and applications. Nanoparticles, integral components of nanostructures, manifest unique physical and chemical traits divergent from bulk materials, rendering them appealing for diverse industrial uses. The review provides a detailed categorization of nanomaterials based on dimensions, encompassing 1D (surface films), 2D (monolayer materials like graphene), and 3D (bulk powders, nanoparticle dispersions). Synthesis methods, classified as top-down (breakdown) and bottom-up (build-up), are meticulously outlined, covering techniques such as dry/wet grinding, chemical vapor deposition, and liquid-phase methods. The synthesis methods and applications of metal sulphides, specifically Cadmium Sulphide (CdS), Nickel Sulphide (NiS), and Copper Sulphide (CuS), are explored in terms of crystal structures, quantum size effects, and their roles in solarcells, bioimaging, and photocatalysis. In conclusion, this review presents a comprehensive exploration of nanomaterials, synthesis methodologies, and the distinct applications of metal sulphides. The unique nanoscale properties of these materials hold promise for significant advancements across various fields, spanning from electronics to energy storage.
