Abstract: A moisture adsorption composition that is a vacuum dried powder, that is a metal chloride-impregnated, nanoporous material including a crystallization reaction product of an aluminum precursor and a dicarboxylic acid organic ligand having an average particle diameter of 100 to 2,000 nm, a pore size of 0.6 to 1.7 nm, and a maximum moisture adsorption amount of from 0.2 to 0.9 g/g within a driving pressure (P/P0) that ranges from 0.1 to 0.3. The composition is prepared by synthesizing the nanoporous material by a crystallization reaction between the aluminum precursor and the dicarboxylic acid organic ligand; heat-treating to purify the nanoporous material; impregnating the nanoporous material by mixing with a metal chloride solution in water having a weight ratio of the metal chloride to the nanoporous material of 10:2.5 to 10:50; drying the mixture; crushing the dried product; and vacuum drying the crushed product to provide the moisture adsorption composition.
