MFU-4 - A Metal-Organic Framework for Highly Effective H-2/D-2 Separation

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
