Abstract

Graphical abstract: Abstract: We report on the synthesis of a two-dimensional transition metal carbide, Mo2 C, (MXene) obtained by immersing Mo2 Ga2 C thin films in hydrofluoric acid. Experimental evidences for neither synthesis of a Mo-based MXene nor selective etching of Ga from an atomic nanolaminate have previously been presented. MXene formation is verified through X-ray diffraction, transmission electron microscopy, and energy dispersive X-ray spectroscopy. This discovery unlocks new potential applications for Mo-based MXenes in a host of applications, from thermoelectrics to catalysis and energy storage.
