Combined experimental and computational studies on preferential CO₂ adsorption over a zinc-based porous framework solid

Abstract

Synthesis, characterization and study of selective CO2 adsorption over other small gas molecules on a Zn-based porous framework compound.

A review on modified MOFs as CO2 adsorbents using mixed metals and functionalized linkers

“…Recent study reported enhanced CO2 adsorption on a mixed ligand mofs, [Zn2(H2O)(nic)(pyrz)]nnH2O, fig. 10, where H3pyrz and Hnic are respectively pyrazole-3,5dicarboxylic acid and isonicotinic acid [60]. The dehydrated framework revealed a carbon-dioxide absorption of 2.2 and 5.7 wt% at 0.15 bar and 12.2 wt% at 298 K. At low partial pressures, this is comparable to H2, N2, and CH4.…”

Selective luminescent sensing of metal ions and nitroaromatics over a porous mixed-linker cadmium(ii) based metal–organic framework

“…Such type of preferential adsorption of gasses is often observed among porous MOFs. 35 Metal-organic frameworks (MOFs) that possess suitable structure for water sorption are of potentially important in application of emerging technologies, such as adsorptive heat transformation, water harvesting from moist air, desalination etc. 89 Presence of free -NH 2 functionality in the porous framework makes the study of water vapor sorption on Cd-MOF1 relevant as was the case of CO 2 .…”

“…Framework compound and its dehydrated product displayed very selective CO 2 adsorption with respect to other small gas molecules like H 2 , N 2 , CH 4 at low partial pressure. 35 As regards the application of MOFs, luminescent MOFs (LMOFs) have witnessed significant progress along with other applications like catalysis, gas sorption, proton conduction etc. Various molecular processes like ligand-based emission, metal-based emission, emission due to excimer or exciplex formation, guest induced emission etc.…”
