Abstract
The present invention relates to a chabazite zeolite membrane with a controlled pore size and a production method thereof, wherein the sizes of pore space and pore mouth of the chabazite zeolite membrane are finely controlled through chemical vapor deposition. Through the chemical vapor deposition, defects present in the chabazite zeolite membrane are eliminated, and the pore size is effectively controlled. Thus, unlike hydrophilic membranes showing excellent CO/Nseparation performance under a dry condition, the chabazite zeolite membrane with a controlled pore size according to the present invention has a hydrophobic surface, and thus can maintain excellent CO/Nseparation performance even under a wet condition. Accordingly, the chabazite zeolite membrane of the present invention can effectively capture carbon dioxide from nitrogen under various environmental conditions.
