The invention belongs to the technical field of membrane preparation and water purification and discloses a high-performance two-dimensional layered Ti3C2-MXene membrane, a preparation method thereof and an application of the Ti3C2-MXene membrane in
water treatment. The method comprises steps as follows: (1), Ti3AlC2
powder and an HF solution are mixed, stirred for a reaction, centrifugally washed and dried, and Ti3C2
powder is obtained; (2), the Ti3C2
powder and a
solvent are mixed, stirred for the reaction, washed and dried, and treated powder is obtained; (3), the treated powder is dissolved in the
solvent and subjected to ultrasonic treatment and
centrifugation, a liquid supernatant is taken and dried, and a two-dimensional
nanosheet is obtained; (4), a solution is prepared from the two-dimensional
nanosheet and deposited on a
porous substrate with a nano self-
assembly technology, and the high-performance two-dimensional layered Ti3C2-MXene membrane is obtained. The membrane has ultrahigh water flux, higher selectivity and good
mechanical property and stability; the method is simple, low in
energy consumption and cost, good in
repeatability and wide in applicability.
