2.2 Preparation of MXene nanosheets
In this study, monolayer or multilayer
Ti3C2TX(ML-Ti3C2TX, MXene) was
obtained by mild selective etching of the Al layer in
Ti3AlC2 (MAX) by HCl and LiF using
commercial Ti3AlC2 powder with 200 mesh
as a precursor. The MXene nanosheet solution was prepared in accordance
with our previous work for subsequent membrane
assembly.42 The
schematic diagram of the fabrication process of
Ti3C2TX MXene nanosheets
is shown in Figure 1A.
