Modification of ZIF‐8 Membranes for Gas Separation Using X‐ray Radiation

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, CO2 permeance decreases by only 9%, while N2 and CH4 permeances reduce by 75 and 65%, respectively, leading to 3.7‐ and 2.6‐fold enhancements in ideal selectivity for CO2/N2 and CO2/CH4.
