| Abstract Scope |
MXenes have emerged as promising energy-storage materials due to their high electrical conductivity, tunable surface chemistry, and layered structure. Developing rapid, safe, efficient, and scalable synthetic routes is essential for advancing their practical production and application. Here, we report a solvent-free mechanochemical strategy for synthesizing Ti₃C₂Tₓ MXene by ball milling Ti₃AlC₂ MAX phase with fluoride salt, enabling selective Al removal and MXene formation without liquid solvents. Nitrogen-doped Ti₃C₂Tₓ MXenes were further prepared by introducing melamine during ball milling, providing a simple route for simultaneous MXene synthesis and heteroatom doping. The resulting materials were characterized to evaluate their structure, morphology, surface chemistry, and nitrogen incorporation. As lithium-ion battery anodes, the mechanochemically synthesized Ti₃C₂Tₓ MXenes showed improved Li-ion storage performance compared with Ti₃C₂Tₓ prepared by a conventional thermal-treatment-based method, while N-doping further enhanced electrochemical performance. |
