In addition, this is the first time that exclusively Cl-terminated MXenes were obtained, and the etching effect of Lewis acid in molten salts provides a green and viable route to preparing MXenes through an HF-free chemical approach. These results indicate that A-site element replacement in traditional MAX phases by late transition-metal halides opens the door to explore MAX phases that are not thermodynamically stable at high temperature and would be difficult to synthesize through the commonly employed powder metallurgy approach. When employing excess ZnCl 2, Cl-terminated MXenes (such as Ti 3C 2Cl 2 and Ti 2CCl 2) were derived by a subsequent exfoliation of Ti 3ZnC 2 and Ti 2ZnC due to the strong Lewis acidity of molten ZnCl 2. ![]() Using this replacement reaction between the Zn element from molten ZnCl 2 and the Al element in MAX phase precursors (Ti 3AlC 2, Ti 2AlC, Ti 2AlN, and V 2AlC), novel MAX phases Ti 3ZnC 2, Ti 2ZnC, Ti 2ZnN, and V 2ZnC were synthesized. The approach is a top-down route that enables the late transitional element atom (Zn in the present case) to occupy the A site in the pre-existing MAX phase structure. Here, we demonstrate a general approach to synthesizing a series of Zn-based MAX phases and Cl-terminated MXenes originating from the replacement reaction between the MAX phase and the late transition-metal halides. Nanolaminated materials are important because of their exceptional properties and wide range of applications.
