Overview

Experimental study reveals exceptional moisture-tolerant carbon capture in porous coordination polymers, highlighting a robust microenvironment design for industrial flue gas separations.

Key Points

To develop moisture-tolerant porous adsorbents that overcome the trade-off between high carbon dioxide affinity and competitive water adsorption during industrial carbon capture.
Synthesized a series of isostructural porous coordination polymers (PCP-H, PCP-NH2, and PCP-OH) featuring corrugated channels with parallel aromatic hydrophobic walls and tunable polar sites.
Evaluated carbon dioxide breakthrough performance, gas selectivity, and cycling stability under simulated flue gas with 70% relative humidity and trace sulfur dioxide across 99 cycles.
Investigated guest-host binding mechanisms using in situ single-crystal X-ray diffraction, diffuse reflectance infrared Fourier transform spectroscopy, and grand canonical Monte Carlo simulations.
PCP-NH2 exhibited superior carbon dioxide over nitrogen selectivity compared to its non-functionalized and hydroxylated analogues.
PCP-NH2 retained 95% of its carbon dioxide capacity at 70% relative humidity, even with trace sulfur dioxide, maintaining fast kinetics and stable performance over 99 cycles.
Structural analyses showed carbon dioxide molecules are stabilized via cooperative C=O···H and π···π interactions in clip-like traps, while hydrophobic walls suppress water uptake.
