We report on the synthesis of the first two-dimensional transition metal nitride, Ti4N3-based MXene. In contrast to the previously reported MXene synthesis methods - in which selective etching of a MAX phase precursor occurred in aqueous acidic solutions - here a molten fluoride salt is used to etch Al from a Ti4AlN3 powder precursor at 550 °C under an argon atmosphere. We further delaminated the resulting MXene to produce few-layered nanosheets and monolayers of Ti4N3Tx, where T is a surface…

Thickness biased capture of CO2 on carbide MXenes.

The possibility to tune the CO2 interaction based on the MXene thickness is further investigated by means of kinetic phase diagrams, providing additional evidence that carbide MXene surfaces are promising materials for CO2 capture even at low CO2 partial pressures, and that theMXene thickness can be used to fine tune this appealing behavior.

New Method for the Synthesis of 2D Vanadium Nitride (MXene) and Its Application as a Supercapacitor Electrode

A novel synthesis of V2NTx (Tx is the surface termination) obtained by the selective removal of “Al” from V2AlN by immersing powders of V 2AlN in the LiF–HCl mixture (salt–acid etching) followed by sonication to obtain V2 NTx (tx = −F, −O) MXene which is then delaminated using the dimethyl sulfoxide solvent.
