Tailoring the pore structure modified with functional groups for superior CO2 adsorption capacity and the selectivity of separation

Xuefei An et al.

Summary: This study developed ultra-uniform N-doped carbon spheres for efficient CO2 adsorption and high selectivity in simulated ultra-low emission flue gas. The fabrication method and the relationship between porous structures and CO2 adsorption capacity were explored, resulting in an optimized adsorbent with high performance and selectivity. Compared to other adsorbents, this promising ANG-Cs shows potential for controlled CO2 adsorption and separation in industry applications of ultra-low emission gas.

Comprehensive Assessment of the Accuracy of the Ideal Adsorbed Solution Theory for Predicting Binary Adsorption of Gas Mixtures in Porous Materials

Farhad Gharagheizi et al.

Summary: This paper systematically evaluates the accuracy of the ideal adsorbed solution theory (IAST) for gas adsorption using a large collection of binary experimental data, which will be valuable for future efforts to test or develop mixing theories that improve upon FAST. This analysis includes data from 63 gas mixtures of 37 different molecular species and 174 different adsorbents, making it the most systematic evaluation to date of the accuracy of IAST for gas adsorption.

Single-Phase Covalent Organic Framework Staggered Stacking Nanosheet Membrane for CO2-Selective Separation

Pengyuan Wang et al.

Summary: Three types of high-quality beta-ketoenamine-type COF nanosheets with different pore sizes were developed and aggregated into ultrathin nanosheet membranes with distinctive staggered stacking patterns. The narrowed pore sizes derived from the micro-structures and selective adsorption capacities synergistically endowed the COF membranes with intriguing CO2-philic separation performances, among which TpPa-2 with medium pore size exhibited an optimal CO2/H-2 separation factor of 22 and a CO2 permeance of 328 gas permeation units at 298 K. This membrane performance reached the target of commercial feasibility for syngas separations.
