“…However, the lower atomic weight of metal does not completely explain the enhanced capacity of MOFs. The relative humidity in the gases or the exposure of MOFs to water has substantial influences on the adsorption of CO 2 (Cho et al 2012). However, there would be no apparent changes in the powder X-ray diffraction (PXRD) patterns for the water-exposed samples, but the BET surface area was extensively reduced up to 50 % (more than 50 % in the case of Cu-BTC and Mg-MOF-74).…”

In the last few decades of industrialization, the concentration of CO 2 in the atmosphere had increased rapidly. Different organizations have invested considerable funds in research activities worldwide for CO 2 capture and storage. To date, significant work has been done and various technologies have been proposed for CO 2 capture and storage. Both adsorption and absorption are promising techniques for CO 2 capture, but low-temperature adsorption processes using solid adsorbents are the prevailing technique nowadays. In this review paper, a variety of adsorbents such as carbonaceous materials, dry alkali metal-based sorbents, zeolites, metal-organic frameworks (MOFs) and microporous organic polymers (MOPs) have been studied. Various methods of chemical or physical modification and the effects of supporting materials have been discussed to enhance CO 2 capture capacity of these adsorbents. Low-temperature (\100°C) adsorption processes for CO 2 capture are critically analyzed and concluded on the basis of information available so far in the literature. All the information in CO 2 adsorption using different routes has been discussed, summarized and thoroughly presented in this review article. The most important comparative study of relatively new material MOFs and MOPs is carried out between the groups and with other sorbent as well.

“…Co-MOF-74 has also been tested in a similar reaction, addition of CO 2 onto styrene oxide, but without a co-catalyst. [ 137 ] A 96% conversion was observed in 4 h but the reaction was operated at elevated pressure and temperature (20 atm and 100 °C). Also a toxic solvent, chlorobenzene, is required.…”

Carbon capture and storage (CCS) technologies aiming at tackling CO2 emission have attracted much attention from scientists of various backgrounds. Most CCS systems require an efficient adsorbent to remove CO2 from sources such as fossil fuels (pre‐combustion) or flue gas from power generation (post‐combustion). Research on developing efficient adsorbents with a substantial capacity, good stability and recyclability has grown rapidly in the past decade. Because of their high surface area, highly porous structure, and high stability, various nanoporous materials have been viewed as good candidates for this challenging task. Here, recent developments in several classes of nanoporous materials, such as zeolites, metal organic frameworks (MOFs), mesoporous silicas, carbon nanotubes, and organic cage frameworks, for CCS are examined and potential future directions for CCS technology are discussed. The main criteria for a sustainable CO2 adsorbent for industrial use are also rationalized. Moreover, catalytic transformations of CO2 to other chemical species using nanoporous catalysts and their potential for large scale carbon capture and utilization (CCU) processes are also discussed. Application of CCU technologies avoids any potential hazard associated with CO2 reservoirs and allows possible recovery of some running cost for CO2 capture by manufacturing valuable chemicals.

“…Mesoporous molecular sieves (Gil et al, 2011;Wang et al, 2012;Xu et al, 2003) are widely used as adsorbents for gas separation because of the high surface area, large pore volume and tunable pore size. Metal-organic frameworks (MOFs) (Cho et al, 2012;Ganesh et al, 2014;Xian et al, 2015) have caused extensive concerns in the recent years due to the notably high surface area, controllable pore structure and pore surface property, and relevant researches on this field of CO 2 adsorption are on the rise.…”

Activated carbon aerogel (CA)-based amine-loaded adsorbent has been successfully developed for CO 2 capture. The adsorbents were characterized by scanning electron microscope (SEM), Fourier transform infrared spectroscopy (FT-IR), N 2 adsorption/desorption and thermogravimetric analysis (TGA). The CO 2 adsorption performance was tested by the fixed bed system at 5% CO 2 concentration. The effects of the mass ratio of KOH to CA, type of amine, amine loadings, addition of polyethylene glycol (PEG) or surfactants and adsorption temperature on the CO 2 capture performance of amine-loaded activated CA as well as the regeneration capability were examined. The results show that the adsorbents effectively remove 5% CO 2 from gas mixtures. The optimum adsorption temperature and amine loadings of polyethyleneimine (PEI)-loaded activated CA are 75°C and 55 wt.% respectively at the activation mass ratio KOH to CA of 1. Under these optimum conditions, the PEI-loaded activated CA reaches the highest adsorption capacity of 2.06 mmol g -1 adsorbent. Addition of PEG facilitates the CO 2 adsorption. Suyadal's and Yasyerli's deactivation models both fit the experimental breakthrough curves of tetraethylenepentamine (TEPA)-loaded activated CA better than that of PEI-loaded activated CA. The adsorption kinetics nonlinear fitting results show that the adsorption process follows Bangham model.
