| Abstract Scope |
MXenes are two-dimensional (2D) transition metal carbides and nitrides with the general formula Mn+1XnTx, where M is an early transition metal, X is carbon and/or nitrogen (n = 1–4), and Tx represents surface terminations (e.g., O, OH, F, Cl, I). They are electrically conductive and can accommodate ions between their layers, making them attractive for a wide range of applications including electrochemical energy storage, water purification, catalysis, and biomedical technologies. Incorporating MXenes into hybrids with organic molecules further expands their potential. Here, we discuss several examples of MXene–organic hybrid synthesis and their applications in electrochemical energy storage. For instance, intercalating alkylammonium chains between Ti3C2Tx layers significantly enhances their performance as supercapacitor electrodes in room-temperature ionic liquids. We also highlight recent advances in using MXene hybrids as sorbents for radioactive iodine. |
