“…[16] Among a variety of materials reported in this category, this section describes in detail adsorption on a representative oxide, calcium oxide, along with a discussion of other important metal-based adsorbents including magnesium oxides and lithium zirconates. Although we focus attention here on calcium oxides and magnesium oxides, it should be noted that many other metal oxides display some CO 2 adsorption properties under selected conditions including lithium oxides, [98] sodium oxides, [99][100][101][102] potassium oxides, [103,104] rubidium oxides, [105] cesium oxides, [106] barium oxides, [107] iron oxides, [108][109][110][111][112] tantalum oxides, [113] copper oxides, [114,115] chromium oxides, [116][117][118][119][120] and aluminum oxides.

Since the time of the industrial revolution, the atmospheric CO(2) concentration has risen by nearly 35 % to its current level of 383 ppm. The increased carbon dioxide concentration in the atmosphere has been suggested to be a leading contributor to global climate change. To slow the increase, reductions in anthropogenic CO(2) emissions are necessary. Large emission point sources, such as fossil-fuel-based power generation facilities, are the first targets for these reductions. A benchmark, mature technology for the separation of dilute CO(2) from gas streams is via absorption with aqueous amines. However, the use of solid adsorbents is now being widely considered as an alternative, potentially less-energy-intensive separation technology. This Review describes the CO(2) adsorption behavior of several different classes of solid carbon dioxide adsorbents, including zeolites, activated carbons, calcium oxides, hydrotalcites, organic-inorganic hybrids, and metal-organic frameworks. These adsorbents are evaluated in terms of their equilibrium CO(2) capacities as well as other important parameters such as adsorption-desorption kinetics, operating windows, stability, and regenerability. The scope of currently available CO(2) adsorbents and their critical properties that will ultimately affect their incorporation into large-scale separation processes is presented.

“…Most available works in the open literature are directed on high temperature solid sorbents like lithium zirconate (Li 2 ZrO 3 ) [4,5], sodium zirconate (Na 2 ZrO 3 ) [6,7], lithium silicate (Li 4 SiO 4 ) [8][9][10] and CaO-based sorbents [11][12][13]. High CO 2 sorption capacity and adsorption/desorption kinetics rate, relatively mild regeneration temperature, and multicycle stability are the most important parameters to be taken into account.…”

“…[8][9][10][11][12][13] As described in our previous paper, 14 in the literature, there are many experimental works on Li 2 ZrO 3 capture CO 2 , but only have few reports on CO 2 capture by Na 2 ZrO 3 and K 2 ZrO 3 . Lopez-Ortiz et al 15 compared the CO 2 capture performance of Na 2 ZrO 3 with Li 2 ZrO 3 and Li 4 SiO 4 and found that Na 2 ZrO 3 has better performance. Their experimental data showed that Na 2 ZrO 3 presented highest sorption rate and can absorb almost 100% of the maximum theoretical CO 2 sorption compared to 70% and 80% of Li 2 ZrO 3 and Li 4 SiO 4 .…”

Isotopic effect on the vibrational lifetime of the carbon-deuterium stretch excitation on graphene J. Chem. Phys. 135, 114506 (2011) Vibrational properties of graphene fluoride and graphane Appl. Phys. Lett. 98, 051914 (2011) Electronic structural and electrochemical properties of lithium zirconates and their capabilities of CO2 capture: A first-principles density-functional theory and phonon dynamics approach J. Alkali metal zirconates could be used as solid sorbents for CO 2 capture. The structural, electronic, and phonon properties of Na 2 ZrO 3 , K 2 ZrO 3 , Na 2 CO 3 , and K 2 CO 3 are investigated by combining the density functional theory with lattice phonon dynamics. The thermodynamics of CO 2 absorption/desorption reactions of these two zirconates are analyzed. The calculated results show that their optimized structures are in a good agreement with experimental measurements. The calculated band gaps are 4.339 eV (indirect), 3.641 eV (direct), 3.935 eV (indirect), and 3.697 eV (direct) for Na 2 ZrO 3 , K 2 ZrO 3 , Na 2 CO 3 , and K 2 CO 3 , respectively. The calculated phonon dispersions and phonon density of states for M 2 ZrO 3 and M 2 CO 3 (M ¼ K, Na, Li) revealed that from K to Na to Li, their frequency peaks are shifted to high frequencies due to the molecular weight decreased from K to Li. From the calculated reaction heats and relationships of free energy change versus temperatures and CO 2 pressures of the M 2 ZrO 3 (M ¼ K, Na, Li) reacting with CO 2 , we found that the performance of Na 2 ZrO 3 capturing CO 2 is similar to that of Li 2 ZrO 3 and is better than that of K 2 ZrO 3 . Therefore, Na 2 ZrO 3 and Li 2 ZrO 3 are good candidates of high temperature CO 2 sorbents and could be used for postcombustion CO 2 capture technologies.
