MXene‐Based Capacitive Deionization–Strong Competitor Among Faradaic Electrode Systems: Current Status and Future Perspectives

“…Carbon-coated CoÀ Fe alloy nanoparticles (Co 3 Fe 7 @C) is also employed recently as a Cl À capturing electrode with excellent desalination performance (Cl À SAC/ ASAR: 72.29 mg g À 1 /2.41 mg g À 1 min À 1 , 110 % Cl À SAC retention after 100 cycles). [215] Applicability of the shuttle-like FeP as a Cl À capturing Faradaic electrode material in the HCDI device showed a high SAC of 79.09 mg g À 1 at 1.2 V due to the conversion of Fe 2 + to Fe 3 + accompanied by FeÀ Cl bond formation. [216] Therefore, a high SAC achieved by CoFe-LDH/Ti 3 C 2 T x (149.25 mg g À 1 ), [209] a high Cl À removal capacity of the Ti 3 C 2 T x /Ag (135 mg g À 1 ), [208] and an excellent SAC (95.7 mg g À 1 )/ASAR (9.57 mg g À 1 min À 1 ) of the Bi-ene NSs@Ti 3 C 2 T x [210] are remarkable achievements, which approves a prestigious status of the MXene-based electrodes in Cl À based desalination (Table 1, 2).…”

“…performed an efficient removal of the Cl − by Fe 3 C@graphene/chitosan‐derived N‐doped carbon (GNC) with slightly lower Cl − SAC (82.08 mg g −1 at 1.4 V, 80.08 mg g −1 @ 0.02 A g −1 ) compared to the previous report, [213] but the ASAR (~2.74 mg g −1 min −1 at 1.4 V) and number of regeneration cycles (74.2 % SAC retention after 150 cycles) significantly improved. Carbon‐coated Co−Fe alloy nanoparticles (Co 3 Fe 7 @C) is also employed recently as a Cl − capturing electrode with excellent desalination performance (Cl − SAC/ASAR: 72.29 mg g −1 /2.41 mg g −1 min −1 , 110 % Cl − SAC retention after 100 cycles) [215] .
