Pore size effect of 1,3,6,8-tetrakis(4-carboxyphenyl)pyrene-based metal-organic frameworks for enhanced SF6 adsorption with high selectivity

Selective Cu and Ni-MOFs as pre-catalysts for the hydrogenation of furfural to furfuryl alcohol

“…6b). 48,49,51 The 1 H NMR spectra for both activated samples after digestion also revealed the disappearance of the DMF proton peaks thus further supporting successful activation (Fig. SI 5 and SI 6†).…”

“…6b). 48,49,51 The 1 H NMR spectra for both activated [52][53][54] Elemental mapping for both MOFs showed that all elements were uniformly distributed within the MOFs matrix. In addition, the EDX micrographs obtained from cubic crystals showed that the elemental composition for MOF 1 and MOF 2 was mainly (C, O, N, Cu) and (C, O, N, CI, Ni), which suggested successful formation of both compounds.…”

A hexagon based Mn(ii) rod metal–organic framework – structure, SF6gas sorption, magnetism and electrochemistry

“…The SF 6 /N 2 selectivity of CTH-18 is thus slightly lower than some highly SF 6 selective MOFs such as Yb-TBAPy or UU-200. 6,14 However, the SF 6 uptake on CTH-18 at 0.1 bar was higher than many other MOFs, including Zn-MOF-74 (∼1.35 mmol g −1 at 298 K) 16 UiO-66-Zr (∼0.75 mmol g −1 at 298 K) 17 or SU-100 (∼1.08mmol g −1 at 298 K). 18…”

“…4 An emerging application is the capture of SF 6 , a greenhouse gas some 22 000 times more potent than CO 2 , used in industrial settings because of its dielectric properties, its non-toxicity, and thermal stabilty. 5,6…”

“…As the pore size of CTH-18 was similar to the size of the kinetic diameter of the adsorbate gas (SF 6 ), enhanced van der Waals interaction between the pore surface and the adsorbate gas was expected. 6,14,15 The enhanced interaction was reflected by the high isosteric heat of SF 6 adsorption (∼40–50 kJ mol −1 ).…”
