Selectivity of ILs to CO2 is higher than H2, N2, O2 and comparable with SO2 and H2S. • FUN-AILs + amine achieved 1:1 reaction stoichiometry higher than CO2–amine process. Abstract Global warming triggered by greenhouse gas (GHG) emissions, particularly carbon dioxide (CO2), significantly...
in which C is a constant that depends on the type of crystal structure; Z+and Z–are the charges on the ions; and Rois the interionic distance (the sum of the radii of the positive and negative ions). Thus, the lattice energy of an ionic crystal increases rapidly as the charges of...
charge transferelectric double layermechanismThe increasing emission of carbon dioxide (CO2) caused by the unrestrained consumption of fossil fuels in recent hundreds of years, has caused global environmental and social problems. Meanwhile, CO2 is a cheap, abundant and renewable C1‐feedstock, which ...
The activities of as-synthesized samples were evaluated for the gas-phase CO2photoreduction under irradiation by the 300 W Xenon lamp (Fig.2a). By altering the boric acid amount, the best performance for bCN was obtained with CO, CH4, and H2(3.9, 1.7 and 1.7 μmol g−1h−1) as the...
of the ions increase and the sizes of the ions decrease. When all other parameters are kept constant, doubling the charge of both the cation and anion quadruples the lattice energy. For example, the lattice energy of LiF (Z+and Z–= 1) is 1023 kJ/mol, whereas that of MgO (Z+and ...
Ion pair speciation of ionic liquids (ILs) has an important effect on the physical and chemical properties of ILs and recognition of the structure of ion pairs in solution is essential. It has been reported that ion pairs of some ILs can be formed by hydrogen bonding interactions between catio...
Two task-specific PIL coatings, i.e., poly(VHIM-NTf2) and poly(VHIM-taurate), were recently synthesized and were used in the SPME of CO2.25 The procedure for the synthesis of the two PILs is shown in Figure 3. The poly(VHIM-NTf2) PIL contains the NTf2− anion. ILs consisting...
