Abstract
Provided is a method for producing zeolite having a controlled aluminum content, wherein the sodium hydroxide molar concentration of a zeolite synthesis mixture can be adjusted to adjust the aluminum content in synthesized CHA. The structure of the low aluminum-content CHA produced by the provided method does not collapse even after high-temperature hydrothermal treatment, and thus the catalytic activity of the CHA can be maintained. Moreover, by adjusting the aluminum content in the framework, the properties of the produced CHA significantly change, and thus the CHA can be applied to various fields.
