Nanoporous materials for hydrogen isotope separation Video: https://tugraz.webex.com/tugraz/j.php?MTID=m515e47db70524775a7f5460d95f963c6 One of the important operations in chemical industry is separation and purification of gaseous products. Especially H$_2$/D$_2$ isotope separation is a difficult task since its size, shape and thermodynamic properties resemble each other. Porous materials offer two different mechanisms for separating hydrogen isotopes, either confinement in small pores, i.e., “kinetic quantum sieving”, or adsorption on strong binding sites, i.e., “chemical affinity quantum sieving”. Recently, several new classes of nanoporous materials have been developed, which for the first time allow the exact tailoring of pore size and aperture as well as including open metal sites into the framework. |
