Microwave synthesis and gas sorption of calcium and strontium metal-organic frameworks with high thermal stability

Two new calcium and strontium metal-organic frameworks [Ca(SBA)] (CYCU-1) and [Sr(SBA)] (CYCU-2) were prepared by microwave-assisted reactions. Both rigid frameworks are thermally stable up to about 450 degrees C. As verified by N-2, CO2, and H-2 sorption measurements, the thermally activated CYCU-1 and CYCU-2 exhibit significant microporosity.
