MXene, a new 2D transition metal carbide-based material, is gaining outstanding attention in recent days in the area of separation and purification. In this study, we have successfully synthesized vanadium-based MXene-V₂CT_x (where T represents functional groups such as –OH, O, and F) by etching an aluminum layer from V₂AlC. For the first time, a vanadium-based MXene-V₂CT_x-embedded mixed matrix membrane was fabricated and utilized for removal of hazardous dye and humic acid from wastewater. With an increase in V₂CT_x loading, the hydrophilicity of the polyphenylsulfone (PPSU) membrane reasonably improved, and its water contact angle was reduced from 82.8 to 70.9°. V₂CT_x nanosheet-embedded PPSU membrane exhibited an excellent pure water permeability of 247 L m^–2 h^–1, which was 266% elevated than the pristine PPSU membrane. The V₂CT_x-PPSU membrane revealed a good …
