| Abstract Scope |
2D transition metal carbides and nitrides (MXenes) are a large family of earth-abundant materials with more than sixty compositions synthesized since 2011. MXenes exhibit properties such as electrochemically active 2D surfaces, hydrophilicity, high electrical conductivity, and an affinity to bond with molecules and nanomaterials to form hybrid structures. In 2021, we reported the first high-entropy MXenes, 2D carbides with four or more principal elements, such as TiVCrMoC3Tx and TiVNbMoC3Tx. Here, we present the expansion of the 2D MXene compositional space with several of our novel chemically complex MXenes, incorporating a combination of group 4, 5, and 6 transition metals to understand the fundamentals of high-entropy effects in these 2Ds. Additionally, we introduce the first tungsten-containing M3C2 MXene made from a covalently bonded layered carbide. We will demonstrate how varying the metal compositions allows for the tunability of MXene properties for different applications. |
