Abstract:
MXene is a new type of highly hydrophilic and negatively charged two-dimensional (2D) nanosheets material for the reasons especially its supernatant has good dispersibility and stability. The MXene supernatant containing several layers was treated as aqueous solvent for interfacial polymerization, consequently the prepared MXene nanocomposite membrane could maintain high perm selectivity even under low pressures required for low carbon footprint. MXene nanocomposite membrane had better hydrophilicity and higher negative charge. Na2SO4 rejection and the pure water flux was improved as compared with the pristine membrane. The MXene nanocomposite membrane also showed the better antifouling property and good stability. Hydrophilic and negatively charged MXene supernatant had better dispersibility and stability. Substituting MXene supernatants of different concentrations for deionized water in aqueous phase, MXene nanocomposite membranes are generally prepared by interfacial polymerization. It was observed that few-layers Ti3C2Tx acted a crucial role in membrane surface modification, so that it improved the hydrophilicity and negative charge of membranes surface and increased surface roughness. Few-layers of MXene nanosheets with excellent hydrophilicity, negative charge and mechanical properties provided an academic basis for the preparation of low-carbon and durable NF membranes with outstanding performance.Two-dimensional titanium carbides can be used to remove toxic dyes like acid blue and methylene blue, for their good adsorption contrast to other twodimensional materials. In compared to typical adsorbents, the removal efficiencies of the use of MXene in methylene blue, methyl orange, methyl red, congo red, and Evans blue was unusually high.
