HIERARCHICAL NANO POROUS ALUMINOPHOSPHATE HAVING EXCELLENT MOISTURE ADSORPTION AND METHOD OF PRODUCING SAME

摘要

The present invention relates to a moisture adsorbent produced by adsorbing an inorganic salt onto hierarchical nano porous aluminophosphate comprising micropores and mesopores, and more specifically, to hierarchical nano porous aluminophosphate having excellent moisture adsorption which can utilize a large pore volume and moisture absorption properties of the inorganic salt, and to a method of producing the same. An inorganic salt is impregnated in the hierarchical nano porous aluminophosphate having mesopores and micropores formed therein so as to utilize a large pore volume and moisture absorption properties of the inorganic salt. Accordingly, a higher moisture adsorption performance than existing other porous aluminophosphates may be achieved. Particularly, the present invention may provide an adsorbent which shows high moisture adsorbent performance in typical Korean summer conditions, at a temperature of 30-35°C and a relative humidity of 0.1-0.3 (0.56-1.68 kPa), and thus may be used in adsorption-type freezers suitable for such Korean climate conditions.;COPYRIGHT KIPO 2017
