Abstract: Methods for fabrication of and use of magnesium oxide sorbents for room temperature carbon dioxide adsorption are provided. In accordance with one aspect, a method for fabrication of sorbents is provided which includes using calcination to obtain MgO—Mg(OH)2 nano-composites and aging the MgO—Mg(OH)2 nano-composites to form nano MCHs for room temperature carbon dioxide adsorption. According to another aspect, a method for fabrication of sorbents which includes fabrication of monoclinic magnesium malate tetrahydrate (C8H10MgO10.4H2O) and use of such sorbents for room temperature carbon dioxide adsorption is provided.
