Aerogel-like, porous Ti₃C₂T_x MXene architecture electrode displayed a high electroadsorption capacity for capacitive deionization of saline water. A vacuum freeze-drying process was employed to prevent the restacking of MXene nanosheets due to van der Waals forces, leading to the formation of a porous structure with a large specific surface area. When applied as electrode materials for capacitive deionization, porous MXene demonstrated a high specific capacitance of 156 F/g and a volumetric capacitance of 410 F/cm³ in 1 M sodium chloride (NaCl) electrolyte. The porous Ti₃C₂T_x MXene electrodes can deliver a high electroadsorption capacity of 118 mg/cm³ (45 mg/g) in 10,000 mg/L NaCl solution (applied voltage: 1.2 V) and excellent cycling stability (up to 60 cycles) in comparison with the restacked MXene and activated carbon electrodes, indicating its promising potential for desalination applications.

气凝胶状的多孔Ti ₃ C ₂ T _x MXene结构电极对盐水的电容去离子具有很高的电吸附能力。为了防止由于范德华力导致的MXene纳米片的再堆叠，采用了真空冷冻干燥工艺，从而导致形成了具有大比表面积的多孔结构。当用作电容去离子电极材料时，多孔MXene在1 M氯化钠（NaCl）电解质中显示出156 F / g的高比电容和410 F / cm ³的体积电容。Ti ₃ C ₂ T _x MXene多孔电极可提供118 mg / cm的高电吸附能力与重新堆叠的MXene和活性炭电极相比，在10,000 mg / L NaCl溶液（施加电压：1.2 V）中具有³（45 mg / g）和优异的循环稳定性（最多60个循环），表明其在海水淡化应用中具有广阔的前景。
