Control of catenation in CuTATB-n metal–organic frameworks by sonochemical synthesis and its effect on CO2 adsorption

Double-walled pyr topology networks from a novel fluoride-bridged heptanuclear metal cluster

“…Preliminary CO 2 /N 2 selectivity for Tripp-1-Co and Tripp-1-Ni , calculated from the uptakes of CO 2 at 0.15 bar and N 2 at 0.85 bar, are 41.4 and 40.8, 36.8 and 36.7, and 36.2 and 32.9 at 273, 283 and 293 K. These uptakes and selectivities are comparable to many well-known MOMs containing polar functional groups and/or open metal sites, both of which are absent in Tripp-1-M materials. 39 …”

Effect of the structural constituents of metal organic frameworks on carbon dioxide capture

“…It was found that by the simple variation of the power applied, the level of catenation or interpenetration could be controlled. Cu-TATB-60 also showed higher CO 2 capture capacity of 189 mg/g at 273 K, which was constant after five cycles of adsorption and desorption [58]. for CO 2 capture with competitive capture capacities.…”

“…In 2011, Kim et al synthesized catenated and non-catenated forms of CuTATB-n MOF via sonochemistry and measured their CO 2 capture capacities [58]. The sonochemical synthesis was carried out at varying strengths of ultrasonic power, between 20-70% of maximum (maximum being 500 W at 20 kHz).…”

High yield 1-L scale synthesis of ZIF-8 via a sonochemical route

“…The synthesis was then extended successfully to a 1 L-scale with high product yield without compromising the textural properties. As reported previously for MOFs [21][22][23], sonochemical synthesis promotes rapid and homogeneous nucleation through the collapse of acoustic cavitation generated by ultrasonic waves, which results in a substantial decrease in crystallization time accompanied by significant crystal size reduction [21]. ZIF-8 pellets were then prepared from the ZIF-8 powder produced from large scale synthesis and tested as a heterogeneous catalyst for the Knoevenagel condensation reaction.…”
