| Abstract Scope |
MXenes are celebrating their 15th anniversary this year. This first large family of inorganic nanomaterials discovered in the 21st century is comprised of two-dimensional (2D) early transition metal carbides, nitrides, and related structures with a general formula of Mn+1XnTx, where M is a transition metal, X is carbon or nitrogen (oxygen substitution is possible), T represents the surface terminations (O, OH, halogens, chalcogens, etc.), and n = 1—4. MXenes are a rare, once-in-a-generation chemical platform, akin to metal-organic frameworks (MOFs) and quantum dots, that redefine the boundaries between molecules and materials, organic and inorganic compounds, and homogeneous and heterogeneous reactivity. Their properties can be engineered through composition, surface chemistry, and ionotronic modulation. This talk will address wet-chemical and high-temperature selective etching methods, as well as direct gas-phase synthesis of MXenes, and their scalable manufacturing routes from low-cost precursors. |
