Particle size optimization of metal–organic frameworks for superior capacitive deionization in oxygenated saline water

Chemical Communications, Год журнала: 2023, Номер 59(30), С. 4515 - 4518

Опубликована: Янв. 1, 2023

Pyrolysis-free metal-organic frameworks (MOFs) with optimized particle sizes were used as capacitive deionization (CDI) materials in oxygenated saline water. Upon decreasing the size of MOFs, excellent cycling stability and higher CDI performance achieved. This was possibly due to improvement charge transfer electrolyte permeation, uncovering significance control improving performance.

Layered double hydroxides (LDHs) are perceived as a hopeful capacitive deionization (CDI) faradic electrode for Cl- insertion due to its tunable composition, excellent anion exchange capacity, and fast redox activity. Nevertheless, the self-stacking inferior electrical conductivity of two-dimensional structure LDH lead unsatisfactory CDI performance. Herein, three-dimensional (3D) hollow nanocage CoNi-layered hydroxide/carbon composites is well designed anode by cation etching pre-carbonized ZIF-67 template. C/CoNi-LDH has unique 3D abundant pore features, which can effectively suppress sheets facilitate transport ions. Moreover, introduced amorphous carbon layer act conductive network. When employed anode, exhibited high removal capacity 60.88 mg g-1 rate 18.09 min-1 at 1.4 V in 1000 L-1 NaCl solution. The mechanism intercalation pseudo-capacitance reaction revealed electrochemical kinetic analysis ex situ characterization. This study provides vital guidance design high-performance electrodes CDI.

Recent Progress and Challenges in Faradic Capacitive Desalination: From Mechanism to Performance

Small, Год журнала: 2023, Номер 19(33)

Опубликована: Апрель 24, 2023

Due to substantial consumption and widespread contamination of the available freshwater resources, green, economical, sustainable water recycling technologies are urgently needed. Recently, Faradic capacitive deionization (CDI), an emerging desalination technology, has shown great potential due its high salt removal ability, low consumption, hardly any co-ion exclusion effect. However, ion mechanisms structure-property relationships CDI still unclear. Therefore, it is necessary summarize current research progress challenges CDI. In this review, recent from five aspects systematically reviewed: cell architectures, mechanisms, evaluation indicators, operation modes, electrode materials. The working classified as insertion reaction, conversion ion-redox species interaction, couple interaction in electrolytes. intrinsic properties a series Na+ Cl- capturing materials described detail terms design concepts, structural analysis, synthesis modulation. addition, effects different on performance also investigated. Finally, work summarizes remaining provides prospects directions for future development.
