A catalyst includes LTA zeolite including copper ions, wherein a Si/Al ratio of the LTA zeolite is 2 to 50. The catalyst is coated on a honeycomb carrier or a filter. The catalyst removes NOx from a reaction gas at 100&#xb0; C. or above. The catalyst has an NOx conversion rate of 80% at 450&#xb0; C. or above.

Catalyst and method for preparing catalyst

A method for manufacturing a zeolite catalyst includes: manufacturing a first Linde Type A (LTA) zeolite using an LTA seed; manufacturing a second LTA zeolite including ions by substituting ions to the first LTA zeolite; and manufacturing a copper LTA zeolite by performing copper ion exchange on the second LTA zeolite.

Method for preparing zeolite catalyst

A catalyst manufacturing method includes: preparing UZM-35 zeolite; manufacturing ion-containing UZM-35 zeolite by substituting ions in a structure of the UZM-35 zeolite; and manufacturing metal-containing UZM-35 zeolite by exchanging copper (Cu) ions or iron (Fe) ions in a structure of the ion-containing UZM-35 zeolite.
