Ionized Zr-MOFs for highly efficient post-combustion CO2 capture

Enhanced removal of iodide from water induced by a metal-incorporated porous metal–organic framework

“…To verify the permanent porosity of these samples, we carried out N 2 gas sorption isotherms at 77 K, as shown in Correspondingly, the pore volume decreased from 0.66 cm 3 g -1 to 0.40 cm 3 g -1 after silver(I) being loaded. This significant decrease may be attributed to two factors: (a) atomic mass of Ag is far higher than that of H, which increases the mass of MOF; Van der Waals radius of Ag atom is larger than that of H atom, which leads to the decrease of the pore volume [27]; (b) the crystallinity of MOF after Ag + doped is weakened [25,27]. the introduction silver(I) roughens the surface of particles due to the decrease of crystallinity [21].…”

“…To determine the accuracy and veracity of the experimental data, all experiments were repeated for 2-3 times. after Ag + doped, the crystallinity is weakened, but the framework is still retained [25,27]. To verify the permanent porosity of these samples, we carried out N 2 gas sorption isotherms at 77 K, as shown in Correspondingly, the pore volume decreased from 0.66 cm 3 g -1 to 0.40 cm 3 g -1 after silver(I) being loaded.…”

“…Alternatively, a large number of MOFs containing functional groups, such as -COOH, -SO 3 H, have been reported, where the groups can serve as potential metal loaded positions via ion exchange process to expand the functionality of MOFs. However, it is rarely studied as a relatively direct and convenient method [27].…”

Combination of Optimization and Metalated‐Ligand Exchange: An Effective Approach to Functionalize UiO‐66(Zr) MOFs for CO2 Separation

“…g However, the detailed study of exchange rate and its impact on gas uptake is rarely reported. In our previous study, we were able to directly metalate UiO‐66‐(COOH) 2 14h and UiO‐66‐SO 3 H14e by a simple acid‐base reaction and these showed a boost in both CO 2 uptake and CO 2 /N 2 selectivity. Nevertheless, the crystallinity and stability of both original and resultant MOFs are poorly preserved with compromised CO 2 separation performance.…”

Inkjet-printed porphyrinic metal–organic framework thin films for electrocatalysis

“…[1][2][3][4][5][6][7][8][9][10][11][12] The highest Brunauer-Emmett-Teller (BET) surface area of MOFs reported in literature can exceed 7000 m 2 /g, 13 which is much higher than the values of other porous materials. Due to the highsurface-area characteristic of MOF, several recent studies have utilized MOFs as electrode materials for electrochemical applications, [14][15][16][17][18][19] such as supercapacitors, fuel cells, corrosion inhibition, 20 or electrochemical energy storage and conversion.…”
