To address the limitations of current zeolitic adsorbents, various strategies have been developed to enhance their separation performance. These strategies include tuning pore aperture sizes, modifying adsorbent-adsorbate interactions, adjusting adsorbate diffusion rates, and utilizing the "trapdoor" effect. The "trapdoor" effect occurs when a gaseous molecule temporarily displaces a cation positioned at the center of 8MRs, allowing access to the pores and cavities of the zeolite framework .
