A critical review of porous adsorbents for air separation: From fundamental insights to rational adsorbent design

AIChE Journal, Volume 72, Issue 4, April 2026.
Abstract Air separation via selective adsorption using porous adsorbents offers energy‐efficient alternatives to cryogenic distillation for producing high‐purity O2 and N2. Adsorbent efficacy depends on balancing selectivity, durability, and performance consistency across varying conditions. This comprehensive review critically discusses the design and

Systematic model behavior of adsorption on flat surfaces

, 2003
A low density film on a flat surface is described by an expansion involving the first four virial coefficients. The first coefficient (alone) yields the Henry's law regime, while the next three correct for the effects of interactions.

Engineering Active Metal and Nonmetal Sites in Porous Structures of Metal‐Hydroxide Clusters for Enhanced D2/H2 Uptake and Separation

Advanced Science, Volume 13, Issue 13, 3 March 2026.
Two supramolecular assembly frameworks, constructed from metal‐hydroxide clusters, are synthesized via coordination‐driven self‐assembly mediated by Co2+ and Cu2+ metal centers. One of them demonstrates exceptional D2 and H2 uptake capabilities, achieving the second‐highest uptake capacity for D2.
