MXene‐Enhanced Electromembrane Systems for Advanced Water Applications: A Review

Advanced Energy and Sustainability Research, Volume 7, Issue 1, January 2026.
MXenes, synthesized via etching, intercalation, and delamination, exhibit hydrophilicity, conductivity, tunability, and strength, enabling roles as membranes, electrodes, and hybrids in electrical‐driven membrane technologies. These systems leverage adsorption, catalysis, separation, and self‐cleaning but face challenges in stability, scalability ...

Analysis of the theoretical CVC of electromembrane systems [PDF]

E3S Web of Conferences, 2020
In a number of recent studies, the authors derived and substantiated a formula for calculating the theoretical current voltage curve (CVC) of electromembrane systems (EMS). This formula was created for the flow cell of desalination of the electrodiaysis apparatus formed by an anion exchange (AEM) and a cation exchange membranes (CEM) in the ...
