“…It also exhibited high CO 2 uptake (12.3 wt.‐% at 273 K and 1 bar) and acceptable CO 2 /N 2 selectivity (64) . Meanwhile, POPs are proven to be excellent catalysts for CO 2 conversion . In particular, the mesoporosity in the POPs are more favorable for the CO 2 conversion due to the fast transfer rate of the reactants and the products, which makes the active sites of the POPs fully accessible.…”

Due to their tailored porosity, high catalytic activity and excellent chemical/thermal stability, porous organic polymers and their metal complexes hold promising potential in CO 2 capture and conversion. In this work, two kinds of melamine-based porous polymers (TPAMP and TPBMP) and their zinc complexes (Zn-TPAMP and Zn-TPBMP) were synthesized. Zn-TPAMP and Zn-TPBMP present high CO 2 uptake of 11.7 wt.-% and 16.8 wt.-% at 273 K and 1 bar, respectively. In particular, Zn-TPAMP demonstrates high catalytic activity for the cycloaddition of CO 2 with epoxides (TOF: 1383 h -1 ). The high CO 2 For the past decades, the overwhelming CO 2 emission has caused the overall global warming, and 40 % of the CO 2 emissions are released from the fossil fuel-based power plants. Therefore, the post-combustion CO 2 capture is considered to be an effective way for reduction of the CO 2 level in the atmosphere. On the other hand, CO 2 can be served as a cheap and non-toxic block for C 1 chemistry. [1] Thus, CO 2 capture and conversion from the fossil fuel-based power plants have been attracting increasing attention in recent years. In order to achieve effective CO 2 capture various solid materials such as zeolites, metal organic frameworks (MOFs), carbon material, and porous organic polymers (POPs) have been intensively investigated. [2] Among them, POPs hold promising potential due to their tailored porosity, high catalytic activity and excellent chemical/ thermal stability. However, their capability of CO 2 uptake is urgent to be improved to fulfil the practical requirements. Typically, there are two main methods to improve the CO 2 uptake for the POPs: i) Introducing functional groups especially nitrogen-rich functional groups on the skeleton of the POPs. These groups have strong affinity to CO 2 , inducing enhanced CO 2 uptake. Therefore, nitrogen-rich functional groups which have strong affinity to CO 2 , such as azo, [3] imidazole, [4] triazine [5] and amine groups [6] have been frequently grafted to the skeleton of the POPs. For example, Bhunia et al. reported a series of [a] College

The interaction of flue gases (CO 2 , CH 4, and N 2 ) with all-cis 1,2,3,4,5,6-hexafluorocyclohexane(1) and decafluoroadamantane system have been exploited through a systematic computational study to evaluate the capturing efficacy using B3LYP-D3/6-31G(d) level of theory. The DFT results show that 1 is selective for the CO 2 . 1 can adsorb 6 CO 2 molecules with reasonable strength, i. e.,~6.0 to~10.0 kcal/mol. First report with adamantane systems (2, 3), which can adsorb twelve CO 2 molecules with reasonable adsorption energy~À5.0 to À10.0 kcal/mol. Among the three flue gases, CO 2 and CH 4 preferably bind with the polar ÀCÀF bonds whereas N 2 prefers to bind with the ÀCÀH bonds of above systems. The nature of the interaction of CO 2 with these systems has investigated using Atoms In Molecules (AIM), Molecular Electrostatic Potential Surface (MESP), and Energy Decomposition Analysis (EDA) analyses. The dispersive interaction is predominantly responsible for the binding of CO 2 molecule with the ÀCÀF bonds of 1 and AIM calculations also corroborate the noncovalent interactions. The calculated desorption energies suggest that these molecules would be kinetically active to exploit as novel materials to capture flue gases.

“…[3] Moreover, treatment of the waste alkaline solution is an energy intensive process, which may causes econdary pollution to the environment. Recent progresses suggest that some green sorbents, for example, zeolites, [4] zeolitic imidazolate framework, [5][6][7][8] metal-organic framework, [9][10][11][12][13] ionic liquids, [14][15][16][17][18][19][20] base-containing, or porousp olymers, [21][22][23][24][25][26][27][28][29][30][31][32] carbonbased materials, [33,34] are very promising for CO 2 capturew ithout environmental pollution. However, the regeneration of these sorbents upon removing CO 2 has to involve endothermic processes,s till relying on the consumptiono ff ossil fuels.…”

A Reversed Photosynthesis‐like Process for Light‐Triggered CO₂ Capture, Release, and Conversion

et al. 2017

View full text Add to dashboard Cite

Materials for CO capture have been extensively exploited for climate governance and gas separation. However, their regeneration is facing the problems of high energy cost and secondary CO contamination. Herein, a reversed photosynthesis-like process is proposed, in which CO is absorbed in darkness while being released under light illumination. The process is likely supplementary to natural photosynthesis of plants, in which, on the contrary, CO is released during the night. Remarkably, the material used here is able to capture 9.6 wt.% CO according to its active component. Repeatable CO capture at room temperature and release under light irradiation ensures its convenient and cost-effective regeneration. Furthermore, CO released from the system is successfully converted into a stable compound in tandem with specific catalysts.
