“…[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.…”

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.

“…Carbon materials like graphene, zeolites, metal organic frameworks and alkali metal carbonates are also fastly emerging as potential CO 2 adsorbents [8][9][10]. A large number of porous materials like MCM-41, SBA-15, porous silica, clays etc have been reported in the literature; CO 2 adsorption on such porous materials is usually governed by physical adsorption and therefore capacity and selectivity values are generally poor at elevated temperatures [11][12][13][14][15].…”

In this work, porous silica gel-solid beads have been made from economically affordable water-glass precursors via sol-gel nano casting technique. A stable nanometric silica sol was prepared first from water glass and studied for surface potential and sol to gel transition. A free-flow, injectable gel was obtained upon aging the sol which was then assembled into spherical silica beads in a chemical bath. A surface area of 304.7 m 2 g -1 was obtained for water glass derived silica gel beads. These gel beads were impregnated with 3-aminopropyltrimethoxysilane (APTMS) and polyethylenimine (PEI) active functional groups at different percentages for turning the gel beads as sorbents for CO 2 gas adsorption. The effect of amine loading on the thermal stability, morphology as well as porosity was studied and was correlated with CO 2 adsorption values. Depending upon the amount of amine loaded in the gel support CO 2 uptake was found varied. These amine modified silica gel porous adsorbents showed CO 2 adsorption capacity at temperatures as low as 100 o C; samples modified with 15 wt% PEI had CO 2 adsorption capacity of 1.16 mmol g -1 at 50 o C.
