Development of New Materials for Hydrogen Isotopes Separation

Tritium / hydrogen isotopes separation with high efficiency and huge scale is one of the crucial technologies for the realization of deuterium-tritium fusion energy application, and the development of separation methods is highly dependent on the separation materials. This paper provides a state-of-the-art review of hydrogen isotopes separation materials. It contains a brief introduction of advantages, disadvantages and applications of the traditional palladium and Pd-containing materials, and then a detailed summary on three kinds of newly developed materials, i. e., two-dimensional membranes, metal-organic framework (MOF) and zeolites with trapdoor effects, focusing on their separation mechanisms, separation demonstrations, and also some existent problems. Finally, based on that summary, the paper gives suggestions about the directions for future researches and improvements of each type of separation material and potential separation material. © 2023 Cailiao Daobaoshe/ Materials Review.
