“…The remarkable performances of MXenes in electrochemical energy storage systems have been extensively reported, showcasing their potential contributions to technologies such as Li-ion batteries, 14–17 and supercapacitors. 18–21 Additionally, the presence of functional groups (T x ) on the MXene surface can improve its properties, opening up a wider range of chemical formulas and unlocking new applications for these 2D materials, such as electromagnetic interference (EMI) shielding, 22 wearable sensors, 23 photocatalysis, 24–26 poisonous gas sensors, 27–29 volatile organic compounds detectors in meat spoilage assessment, 29 and superconductors. 30,31 One interesting aspect is the existence of MXenes that do not contain functional groups, as demonstrated by Liu et al successfully synthesized high-purity V 2 C MXene, leading to excellent electrochemical performance and high electrical capacity.…”
