The metal-organic framework, MFU-4, possessing small cavities and apertures, is exploited for quantum sieving of hydrogen isotopes. Quantum mechanically, a molecule confined in a small cavity shows an increase in effective size depending on the particle mass, which leads to a faster deuterium adsorption from a H(2)/D(2) isotope mixture.
具有小孔和大孔的金属有机骨架 MFU-4 被用于氢同位素的量子筛分。从量子力学的角度来看，当分子被限制在一个小的空腔中时，其有效尺寸会根据粒子质量的增加而增大，从而导致氘从 H(2)/D(2)同位素混合物中更快地吸附。
