1. A method for manufacturing a modified aluminosilicate, comprising:
a first step of treating an aluminosilicate with an acid;
a second step of primarily calcining the treated material obtained in the first step at 550° C. to 850° C.;
a third step of contacting the calcined material obtained in the second step with a liquid containing one or more elements selected from the group consisting of Group 4 elements and Group 5 elements on the periodic table in a temperature range of 20 to 150° C. to obtain a material; and
a fourth step of drying and secondarily calcining the material obtained in the third step,
wherein a specific surface area of the modified aluminosilicate is 50 to 1000 m2/g, and
the modified aluminosilicate is zeolite having an MSE framework.
