Ti3C2, produced by selective etching of Al from MAX-phase Ti3AlC2, is the most widely studied two-dimensional MXene material in many research fields. However, the synthesis of highly pure Ti3AlC2 typically requires high temperatures, resulting in high-energy demands and high production costs. To reduce the synthesis temperature, we present a new NaCl-assisted approach for synthesizing Ti3AlC2. Ti3AlC2 was synthesized from a Ti2AlC-TiC mixture at 1150 degrees C under an argon atmosphere in a tube furnace. The successful synthesis of highly pure Ti3AlC2 with an ideal crystal structure and the subsequent preparation of Ti3C2 were confirmed by material characterization and simulation results. This molten-salt-assisted method is more efficient in terms of energy and cost because it lowers the synthesis temperature of MAX-phase Ti3AlC2 by 200 degrees C. When assisted by appropriate kind or quantity of molten-salt, the synthesis temperature and synthesis time may be further reduced. These findings may provide a new approach for lower-temperature synthesis of other MAX-phase materials and greatly widen the applications of MAX and MXene materials.
