Separation technologies for hydrogen isotopes such as deuterium and tritium are very important not only for the treatment of radioactive tritiated water, but also for the production of valuable isotopes required for semiconductors, batteries and nuclear fusion industries. Water electrolysis is one of the promising technologies for enrichment of hydrogen isotopes. However, the poor gas barrier property and a low isotopic effect of conventional perfluorosulfic acid (PFSA) membranes result in a safety-related explosion issue and limited separation efficiency. We prepared composite membranes of PFSA covered with atomically thin 2D crystals, such as hexagonal boron nitride and graphene monolayers. We present the enhanced gas barrier property of the membranes and improved separation of hydrogen isotopes by the composite membranes. |
