Heterointerface optimization in a covalent organic framework-on-MXene for high-performance capacitive deionization of oxygenated saline water

in oxygenated saline water, among the state-of-the-art values for CDI electrodes and also exceeding those of most MXene-based or 2D materials. This study highlights the importance of heterointerface optimization in MXene-organic 2D heterostructures to promote CDI of natural (oxygenated) saline water.
