Abstract
The separation of hydrogen isotopes remains a significant\nchallenge\ndue to their nearly identical physicochemical properties. Recently,\nmetal–organic frameworks employing the chemical affinity quantum\nsieving effect have garnered increasing attention for hydrogen isotope\nseparation. In this study, <b>Cu-BTT</b> with open metal sites\nwas synthesized and demonstrated high hydrogen isotope adsorption\ncapacities of 266 cm<sup>3</sup>/g for H<sub>2</sub> and 288 cm<sup>3</sup>/g for D<sub>2</sub>. Dynamic breakthrough experiments revealed\na selectivity of 1.58 at 77 K, highlighting the potential of <b>Cu-BTT</b> as a promising candidate for hydrogen isotope separation.
