Coordination Confined Silver‐Organic Framework for High Performance Electrochemical Deionization

Advanced Science, Год журнала: 2024, Номер 11(28)

Опубликована: Май 2, 2024

Abstract Silver (Ag) is deemed a promising anode material for capacitive deionization (CDI) due to its high theoretical capacity and efficient selectivity Cl − . However, the strong volume change during conversion reaction significantly undermines cycling performance of Ag electrode. Additionally, achieving well‐dispersed in active matrix challenging, as electrodes prepared by conventional thermal reduction tend agglomerate. Herein, organic linker confinement strategy proposed, applying metal–organic framework (MOF) chemistry between nodes ligands construct Ag‐based MOF. The uniform dispersion at molecular level, confined matrix, efficiently enhances utilization sites, strengthens interfacial stability Ag. Consequently, Ag‐MOF CDI exhibits an excellent removal 121.52 mg g −1 20 mA 500 L NaCl solution, rate 60.54%. After 100 cycles, retention 96.93% achieved. Furthermore, capture mechanism elucidated through density functional theory (DFT) calculations, ex situ XRD, Raman XPS. This ingenious electrode design can offer valuable insights development high‐performance applications.

Abstract The environmental toxicity caused by heavy metal ions is always taken seriously. Capacitive deionization (CDI), as an emerging and effective treatment method, widely studied. Among them, the rational design development of efficient electrodes based on high theoretical capacitance, conductivity, stability have great prospects for CDI applications. In this study, a series 2D titanium carbide oxide flakes (2D TCOs) are synthesized using cation‐giving modulation strategy, interlayer spacing materials successfully controlled confining cations (tetraalkylammonium hydroxides, TAAH) with different radii between layers. Interestingly, these TCOs exhibit varying electrochemical properties due to their spacings. flakes‐tetrapropylammonium hydroxide (TCOs‐TPAH) maximum exhibits best performance in sodium ion embedding de‐embedding, capacity 53.11 mg g −1 . addition, capacitive removal efficiency (Fe 3+ , Cr Cu 2+ Cd Co Ni Pb ) can reach over 97% within 2 h. This work presents simple creative strategy bottom‐up synthesis oversized nanomaterials, thus supporting further high‐performance fields energy

Abstract Hybrid capacitive deionization (HCDI) emerges as a burgeoning electrochemical desalination technology due to the utilization of profitable pseudocapacitive reactions. Although tunable organic compounds are potential faradaic electrode materials, their insufficient active sites and high water‐solubility restrict practical HCDI applications. Herein, polymer (PNDS) is proposed with diverse redox‐active for deionization. The pronounced molecular aromaticity strong π‐electron delocalization not only endow PNDS framework rigidity, but refine its electronic structure bolster redox activity electron affinity. As an material, demonstrates substantial capacitance 390 F g −1 sustains long‐term stability at 96.3% after 5000 cycles, surpassing reported Na + ‐capturing electrodes. In‐operando monitoring techniques theoretical calculations reveal efficient capture C═N C═O within during repeated electrosorption processes. conceptual demonstration, high‐performance device equipped exhibits impressive salt removal capacity (66.4 mg ), rapid rate (2.2 min ) stable regeneration property. More importantly, integrated system engineered rapidly repeatedly treat saltwater resources human consumption agricultural irrigation, highlighting promising prospects high‐efficiency
