Rapid and green etching of MAX into MXene phase via a physical process

Abstract

The rapid synthesis of V₂C MXene was achieved by harnessing a synergistic etching route consisting of a dynamic magnetic field and CuCl₂. Within 240 s, the etching process produced MXene in an accordion-like multilayered structure. The obtained V₂C exhibited excellent performance as a lithium-ion battery anode.
