MXenes have aroused intensive enthusiasm because of their exotic properties and promising applications. However, to date, they are usually synthesized by etching technologies. Developing synthetic technologies provides more opportunities for innovation may extend unexplored Here, we report a bottom-up gas-phase synthesis Cl-terminated MXene (Ti2CCl2). The endows Ti2CCl2 with unique surface chemistry, high phase purity, excellent metallic conductivity, which can be used accelerate polysulfide conversion kinetics dramatically prolong the cyclability Li-S batteries. In-depth mechanistic analysis deciphers origin formation offers paradigm tuning chemical vapor deposition. In brief, transforms unlocks hardly achieved potentials MXenes.
