Abstract
Herein we electrochemically and selectively extract Ti from the MAX phase Ti2SC to form carbon/sulfur (C/S) nanolaminates at room temperature. The products are composed of multi‐layers of C/S flakes, with predominantly amorphous and some graphene‐like structures. Covalent bonding between C and S is observed in the nanolaminates, which render the latter promising candidates as electrode materials for Li‐S batteries. We also show that it is possible to extract Ti from other MAX phases, such as Ti3AlC2 , Ti3SnC2 , and Ti2GeC, suggesting that electrochemical etching can be a powerful method to selectively extract the “M” elements from the MAX phases, to produce “AX” layered structures, that cannot be made otherwise. The latter hold promise for a variety of applications, such as energy storage, catalysis, etc.
Carbon/sulfur nanolaminates composed of multilayered C/S flakes with predominantly amorphous, and some graphene‐like, structures were synthesized by electrochemical extraction of Ti from a Ti2SC MAX phase. This approach provides a novel method for the room‐temperature synthesis of “AX” layered structures by the selective extraction of “M” from the MAX phases.
