Abstract
Since their discovery in 2011, the MXene family has rapidly expanded to include nearly 50 unique MXenes. With each new MXene comes unique combinations of properties including high metallic conductivity, high volumetric capacitance, biocompatibility, along with their excellent electrochromic and plasmonic behavior. However, a question that has been raised since their discovery has been: What is the effect of n? In other words, how does the number of layers affect MXene properties? Despite the wide range of synthesized MXenes, there exists no chemistry than spans more than two configurations, limiting the direct study of structure-property relationships in MXenes. This thesis focuses on the synthesis and characterization of new MXenes with the goal of establishing trends of structure-property relationships. To achieve this, first a protocol is established to ensure uniform synthesis across MXenes for more accurate comparison. Next, MXenes in the (Mo2/3V1/3)n+1CnTx (n = 1, 2, 3) system are synthesized, characterized, and their optical, colloidal, electronic, magnetic, and electrochemical properties are explored. Finally, to establish the smallest group of MXenes, the M5X4 family, two new MXenes, Ti2.5Ta2.5C4Tx and Ti2.675Nb2.325C4Tx, are synthesized, characterized, and the properties of this new system explored. Through this, this thesis will provide an overview of MXene structure-property relationships and help guide the discovery and application of future MXenes.
