Porous Aromatic Framework with Multifunctional Sites for Effective Recovery of Various Trace Iodine Species From Water

open access: yesAdvanced Science, EarlyView.
A PAF adsorbent with multifunctional sites framework is developed for the recovery of environment iodine. Benefiting from the high density and accessibility of the favorable Coulomb interaction sites for iodide (I3− and I−) as well as the charge transfer sites for iodine molecules (I2), the PAF adsorbent realizes recording adsorption capacity for ...

Multivariate Covalent Organic Frameworks for High‐Performance Ammonia Nitrogen Separation: Structure‐Property‐Function Relationships

open access: yesAdvanced Science, EarlyView.
Theoretically, this study provides new insights into the atomic‐level adsorption mechanisms and structure‐property‐function relationships of sulfonated COFs for boosting ammonia nitrogen separation. Practically, the findings of this study can guide the design and optimization of COFs and other porous crystalline adsorbents to enhance the capture and ...

Ultra–Efficient and Selective Gold Separation via Second–Sphere Coordination of Aurous Dihalide Using a Nonporous Amorphous Superadsorbent

open access: yesAdvanced Science, EarlyView.
A covalent organic superphane cage serves as a nonporous amorphous superadsorbent for highly efficient and selective gold separation. This material uniquely captures linear aurous dihalide ions, achieving exceptional uptake capacity and selectivity, and proving effective even in seawater, offering a scalable, eco–friendly solution to gold scarcity ...
