Ti–Al–C MAX Phases and Ti–C MXenes via SHS Route and Acid Leaching

Combustion products containing Ti 2 AlC and Ti 3 AlC 2 MAX phases were prepared from Ti–Al–C mixtures by SHS method. The Ti 2 CF 2 MXene was prepared from the Ti 2 AlC MAX phase by leaching out aluminum from a layered structure of MAX phase with hydrofluoric acid. Such an approach can also be applie...

Zusammenfassung:Combustion products containing Ti 2 AlC and Ti 3 AlC 2 MAX phases were prepared from Ti–Al–C mixtures by SHS method. The Ti 2 CF 2 MXene was prepared from the Ti 2 AlC MAX phase by leaching out aluminum from a layered structure of MAX phase with hydrofluoric acid. Such an approach can also be applied to the synthesis of graphene-like carbides, nitrides, and carbonitrides using MAX phases as precursors.
