Exploring Mxenes as Emerging Two-Dimensional Materials for Electrochemical Technologies 

MXenes, a family of two-dimensional transition-metal carbides, nitrides, and carbonitrides, have attracted growing interest as functional materials for electrochemical technologies due to their metallic conductivity, tunable surface terminations, hydrophilic character, and large accessible surface area. In this talk, the development of MXene-based materials as versatile platforms for catalytic and sensing applications will be highlighted, with an emphasis on the structure–property relationships governing charge transfer, surface adsorption, and electrochemical activity. In electrocatalysis, MXene incorporation can facilitate interfacial electron transport, improve active-site accessibility, and promote favorable adsorption of reaction intermediates, thereby enhancing performance in the hydrogen evolution reaction. Beyond energy conversion, MXene-based interfaces also show strong potential for electrochemical sensing, as demonstrated by paraoxon detection, in which surface-active sites and favorable analyte–electrode interactions contribute to sensitive and selective responses. These case studies highlight the multifunctional role of MXenes in bridging sustainable energy conversion and environmental monitoring. The talk will further address current challenges, including oxidation stability, surface chemistry control, and scalable material processing, as key considerations for advancing MXene-based electrochemical systems toward practical applications.
