MXenes are a category of two-dimensional transition-metal carbides, nitrides, and carbonitrides that have attracted an enormous amount of curiosity nowadays since they have their distinctive characteristics, which include hydrophilicity, excellent electrical conductivity, and adaptable surface chemistry. MXenes have special and distinctive properties that enable prospective activity in numerous uses due to their powerful surface chemistry and extensive range of tunability. Given these exceptional qualities, materials with outstanding performance have garnered much interest in the last several years. Much of the research conducted in this chapter relates to particular methods for MXene fabrication. We also go into great length about the production of MXenes using alkaline solution, electrochemical, and salt procedures as well as numerous cleaning routes including acids like hydrochloric acid, hydrofluoric acid, and lithium fluoride. Additionally, a summary of the various fundamental, visual, electronic, and magnetic characteristics of MXenes is provided under their purpose of encouraging elevated levels of physical, chemical, ecological, and electrical stability. Furthermore, MXenes’ versatility can be exploited to develop next-generation batteries, electrocatalysts, and capacitors offering superior productivity and effectiveness. Furthermore, their value in purifying water and environmental sustainability is highlighted by their capacity to absorb and break down contaminants. Supercapacitors, batteries, and solar water desalination. There is also an overview of MXenes’ function of preserving the thermal control capabilities of portable light heaters, or PV/T. Finally, the innovation of MXenes is clarified, and potential suggestions for MXenes are offered to ensure their future use for utility purposes. The goal of the current work is to connect industrial finance with MXene chemistry for energy management technologies. This thorough understanding of MXenes emphasizes their vital relevance to advancing green technologies and addressing ecological problems on an international basis.
