Metal organic gels (MOGs): a new class of sorbents for CO2 separation applications

Abstract

MOGs with excellent thermal stability and porosity have been synthesized at room temperature. The strength of the MOGs obtained depend on the raw materials used, reaction time, 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) suggests 33 wt% (7.5 mmol g−1) of CO2 with a reversible uptake and release. To our knowledge this is the first study on the utilization of the MOGs for CO2 capture applications. Significant uptake of CO2 at high pressure (∼30 bar) clearly reveals the significant potential of these materials for their applications as solid sorbents.
