CO2 capture from flue gas is a costly procedure, usually due to the energy required for regeneration of the capture medium. One potential medium which could reduce such an energy consumption, however, is Na2CO3. It has been well studied as a sorbent, and it is understood that the theoretical energy penalty of use of Na2CO3 for CO2 separation is low, due to the relatively low heat of reaction and low heat capacity of the material. While it offers some advantages over other methods, its primary downfall is the slow reaction with CO2 during adsorption and the slow Na2CO3 regeneration process. An aspect of the invention relates to a catalyst to improve reaction kinetics, and more particularly to a catalyst to improve reaction kinetics for CO2 desorption and CO2 adsorption.
