Seoul National University's College of Engineering, in collaboration with Kookmin University and the Korea Institute of Science and Technology, has announced a major breakthrough in eco-friendly hydrogen production. Led by Professor Jin Young Kim, the team developed a ruthenium-based nanocluster catalyst with a core-shell structure, demonstrating world-class performance and stability in industrial-scale water electrolysis. The catalyst's efficiency surpasses that of platinum while significantly reducing precious metal usage, making it a cost-effective solution for hydrogen production. Published in a prestigious journal, the research signifies a crucial step towards a hydrogen-driven economy. The catalyst's innovative design and high performance have vast applications in hydrogen fuel cells, transportation, and industrial sectors. Dr. Hyun Woo Lim, the study's first author, continues to develop and commercialize the technology as part of Seoul National University's efforts to lead global industry and societal development.
