Abstract
Abstract We report an X‐ray radiation‐induced modification of the structure and gas permeation behavior of ZIF‐8 membranes. With 300 min irradiation time, CO 2 permeance decreases by only 9 %, while N 2 and CH 4 permeances reduce by 75 and 65 %, respectively, leading to 3.7‐ and 2.6‐fold enhancements in ideal selectivity for CO 2 /N 2 and CO 2 /CH 4 .
