Abstract
MXenes are one the most interesting families of 2D materials as they exhibit a variety of properties that make them unique among other 2D materials. These include fast electronic and ionic transport, significant redox activity, high surface charge density, the ability to intercalate many types of ions and molecules, and tunable properties by modifying their composition and surface functional groups. This has led to the exploration of MXenes for an unusually large number of potential applications. In this talk, I will discuss the fundamental properties of MXenes and demonstrate how our group has developed them for use in several applications in electronics, sensing, and energy devices. Specifically, I will discuss applications that capitalize on ionic transport in MXenes and strong redox activity, including salinity gradient energy harvesting and electrochemical devices. Further, I will discuss applications that capitalize on the strong electronic transport in MXenes including using them as contact materials for wide bandgap semiconductor devices, solar cells, and as additives in conductive hydrogels.
