Two-dimensional Ti3C2 layers with
surface groups of OH and/or F
were formed by immersing
Ti3AlC2 powder in concentrated
hydrofluoric acid which results in
selective etching of the Al layers.
Since Ti3AlC2 is a member of a
large family of layered, ternary
carbides and nitrides called MAX
phases, this discovery opens the
door to synthesis of a large
number of 2-D solids with
different chemistries that can be
manipulated to tune properties.
