A unique magnesium-based 3D MOF with nanoscale cages and temperature dependent selective gas sorption properties

A porous Mg-based 3D metal-organic framework with unique nanoscale cages and two-fold interpenetrating pcu nets has been synthesized and characterized. It shows gas-uptake capacities for N-2, H-2, O-2 and CO2 at low temperatures and selective adsorption of CO2 over O-2 and N-2 at room temperature.
