Ti3C2 MXenes-derived NaTi2(PO4)3/MXene nanohybrid for fast and efficient hybrid capacitive deionization performance

Carbon-incorporated Fe3O4 nanoflakes: high-performance faradaic materials for hybrid capacitive deionization and supercapacitors

“…67 To address this issue, hybrid CDI that uses a redox electrode to replace one of the two carbon electrodes has been developed. [68][69][70] Generally, TMOs are good candidates for electrode materials for HCDI, [71][72][73][74] and, recently, Fe 3 O 4 materials have received increasing interest in the HCDI field due to their high desalination performance and great abundance. 75 In this section, we plan to evaluate the potential of our 2D-Fe 3 O 4 /C for HCDI applications.…”

MXene‐Copper/Cobalt Hybrids via Lewis Acidic Molten Salts Etching for High Performance Symmetric Supercapacitors

“…The general formula is M n +1 X n T y ( n =1–3), where M is early d‐block transition metals, X refers to C and/or N, and T stands for surficial functional groups depending on synthetic procedure and post‐synthetic processing [3] . MXenes show great promise in extensive applications, such as energy storage and conversion, [4–6] water purification, [7] catalysts, [8] due to their 2D layered structure, metallic conductivity, and hydrophilic surfaces [9] …”

Graphene–carbon 2D heterostructures with hierarchically-porous P,N-doped layered architecture for capacitive deionization

“…In this regard, capacitive deionization (CDI), an advanced electrochemical deionization technology, has emerged as a competitive methodology for the desalination of brackish water and seawater, due to its several important advantages including low energy consumption, cost effectiveness, and environmental benignity. [5][6][7][8][9] The working principle of CDI is similar to that of electric double layer (EDL) capacitors, 10 where the application of a low directional current causes charged ions to approach the oppositely charged electrode, with their subsequent adsorption at internal pores by formation of EDLs. This process eventually provides puried water with extracted ions being continuously stored within the electrode materials.…”
