KeywordsCO 2 capture, traces CO 2 removal, air capture, physical adsorbents, MOFs AbstractThe capture and separation of traces and concentrated CO 2 from important commodities such as CH 4 , H 2 , O 2 and N 2, is becoming important in many areas related to energy security and environmental sustainability. While trace CO 2 concentration removal applications have been modestly studied for decades, the spike in interest in the capture of concentrated CO 2 was motivated by the need for new energy vectors to replace highly concentrated carbon fuels and the necessity to reduce emissions from fossil fuel-fired power plants. CO 2 capture from various gas streams, at different concentrations, using physical adsorbents, such as activated carbon, zeolites, and metal-organic frameworks (MOFs), is attractive. However, the adsorbents must be designed with consideration of many parameters including CO 2 affinity, kinetics, energetics, stability, capture mechanism, in addition to cost. Here, we perform a systematic analysis regarding the key technical parameters that are required for the best CO 2 capture performance using physical adsorbents. We also experimentally demonstrate a suitable 2 material model of Metal Organic Framework as advanced adsorbents with unprecedented properties for CO 2 capture in a wide range of CO 2 concentration. These recently developed class of MOF adsorbents represent a breakthrough finding in the removal of traces CO 2 using physical adsorption.This platform shows colossal tuning potential for more efficient separation agents.

“…[30][31][32][33] The introduction of abundant uncoordinated nitrogen atoms may produce a stronger interaction with CO 2 . Typically, the interaction between the localized dipoles of a N-containing group and the quadrupole moment of CO 2 could induce dispersion and electrostatic forces to enhance the CO 2 adsorption and separation abilities of MOFs.…”

This metal-organic framework (MOF) exhibited high CO 2 uptake of 79.9 cm 3 cm À3 at 298 K and 100 kPa, as well as excellent adsorption selectivity for CO 2 over CH 4 and N 2 . Particularly, its exceptionally high selectivity of CO 2 over N 2 at 298 K has ranked NENU-520 among the highest MOFs for selective CO 2 separation. Furthermore, the potential application of NENU-520 for the fixed bed pressure swing adsorption (PSA) separation of CO 2 from CH 4 and N 2 has been validated via simulated breakthrough experiments. The small channel with the size of 3.6Å, combined with CO 2 -accessible free nitrogen atoms directed toward the inner surface, is believed to contribute to its high CO 2 uptake capacity and selectivity. Thus, this work represents a unique way to target MOF materials for highly selective CO 2 separation by incorporating CO 2 -philic functional sites on pore surfaces, and at the same time optimizing pore sizes.

Reducing the emission of greenhouse gases, such as CO2 , requires efficient and reusable capture materials. The energy for regenerating sorbents is critical to the cost of CO2 capture. Here, we design a series of photoswitchable CO2 capture molecules by grafting Lewis bases, which can covalently bond CO2 , to azo-based backbones that can switch configurations upon light stimulation. The first-principles calculations demonstrate that intramolecular hydrogen bonds are crucial for enlarging the difference of CO2 binding strengths to the cis and trans isomers. As a result, the CO2 -sorbent interaction can be light-adjusted from strong chemical bonding in one configuration to weak bonding in the other, which may lead to a great energy reduction in sorbent regeneration.
