Abstract: The present invention relates to a preparation method of an organic-inorganic nanoporous material-metal chloride hybrid moisture adsorption composition, and the moisture adsorption composition prepared by the preparation method. More specifically, an embodiment of the present invention provides a preparation method of the moisture adsorption composition, the preparation method comprising the steps of crystallizing an aluminum precursor and a dicarboxylic acid organic ligand to synthesize an organic-inorganic nanoporous material, heat-treating the organic-inorganic nanoporous material to remove unreacted organic materials, mixing the heat-treated organic-inorganic nanoporous material with a metal chloride solution to impregnate particles of the organic-inorganic nanoporous material with a metal chloride, drying the mixture in an oven, thereby removing a solvent from the mixture to obtain a dried product, crushing the dried product to obtain a powder, and vacuum drying the powder to remove residual moisture from the powder. The moisture adsorption composition according to an embodiment of the present invention can be applied to an air conditioner, an adsorption type refrigerator, a dehumidifier, and a cooling and heating device by having a maximum moisture adsorption amount (the amount of moisture adsorbed per unit weight of the adsorption composition) of 0.2 to 0.9 g/g in the driving pressure range (P/P0=0.1 to 0.3).
