The present invention relates to a mesoporous aluminosilicate manufacturing method using decationization and, more specifically, to a mesoporous aluminosilicate manufacturing method which manufactures mesoporous aluminosilicate with micropores and mesopores by gradually breaking an existing zeolite structure by decationization through ion exchange and heat treatment without solid templates or organic silane. The mesoporous aluminosilicate manufactured according to the present invention is economical since synthesis costs are able to be reduced by obtaining mesopores through ion exchange and heat treatment, and is able to be mass-produced. Additionally, the present invention is able to solve endemic problems such as the slow molecular diffusion speed of zeolite only with micropores and is able to control the collapse degree of a zeolite framework and the size of mesopores according to the same by controlling ion exchange. The mesoporous aluminosilicate according to the present invention can be applied as a material capable of being used as a catalyst and an absorbent of large molecules.
