Abstract

The separation of hydrogen isotopes remains a significant challenge due to their nearly identical physicochemical properties. Recently, metal–organic frameworks employing the chemical affinity quantum sieving effect have garnered increasing attention for hydrogen isotope separation. In this study, Cu-BTT with open metal sites was synthesized and demonstrated high hydrogen isotope adsorption capacities of 266 cm³/g for H₂ and 288 cm³/g for D₂. Dynamic breakthrough experiments revealed a selectivity of 1.58 at 77 K, highlighting the potential of Cu-BTT as a promising candidate for hydrogen isotope separation.

具有开放金属位的金属-有机骨架用于D2/H2分离

氢同位素的分离仍然是一个重大的挑战，因为它们几乎相同的物理化学性质。近年来，利用化学亲和量子筛分效应的金属有机骨架在氢同位素分离中受到越来越多的关注。本研究合成了具有开放金属位的Cu-BTT，对H2和D2的氢同位素吸附量分别为266 cm3/g和288 cm3/g。动态突破实验显示，Cu-BTT在77 K下的选择性为1.58，这表明Cu-BTT作为氢同位素分离的有前景的候选材料。
