Prof. Oh Lab at UNIST researches molecular physisorption in nanoporous materials in cryogenic conditions. We exploit such phenomena to solve industrial challenges, such as efficient energy carrier (e.g., hydrogen, methane, etc.) storage and greenhouse gas (e.g., CO2) capture, cost-effective light gas isotope (e.g., H2/D2/T2, 16O/18O, 3He/4He, etc.) separation by quantum sieving, novel H2 boil-off mitigation technology for liquid hydrogen storage and transportation. In particular, efficient hydrogen storage technology will become crucial for the hydrogen economy to achieve carbon neutrality in the future. However, there are still many technical difficulties to be solved, and the main research direction of our team is to solve them. In addition, isotope separation technology using nanoporous materials is spotlighted as a new technology that may replace the expensive cryogenic distillation method. And we are the leading group in these related fields. Moreover, the industrial demand (e.g., semiconductor and display fields) for deuterium is rapidly increasing. Tritium separation and removal technology are also heavily required in nuclear fission and fusion reactors. Therefore, these isotopes separation technology will receive a lot of attention in the near future.
