MOG's with excellent thermal stability and porosity have been synthesized at room temperature. The phase and strength of the MOGs obtained depend on the raw materials used, time, the temperature, concentration of reactants and the processing conditions. MOGs with higher internal surface areas were obtained using near supercritical processing conditions. Measurement of CO2 sorption isotherm of MOG-1a at high pressure (30 bar) suggest 33 wt% (7.5 mmol/g) of CO2 with a reversible uptake and release. To our knowledge this is the first study on the utilization of the MOG's for the CO2 capture applications. Significant uptake of CO2 at high pressure (~30 bar) clearly reveals the significant potential in these materials for their applications as solid sorbents.
