The Korea Research Institute of Standards and Science (KRISS) has achieved a groundbreaking milestone in the realm of green hydrogen production with the development of a highly efficient and cost-effective catalyst. This innovative catalyst, designed for anion exchange membrane (AEM) water electrolysis, addresses the key challenge of using cheaper materials without compromising performance. By combining molybdenum dioxide, nickel, and a small amount of ruthenium, the catalyst not only surpasses existing commercial materials in durability and activity but also demonstrates excellent compatibility with renewable energy sources. The incorporation of ruthenium nanoparticles in the catalyst prevents degradation of molybdenum dioxide, enhancing its long-term performance. The research team's efforts have led to a four-fold increase in durability and a more than six-fold increase in activity compared to current materials, significantly boosting the efficiency of green hydrogen production. Moreover, the catalyst's ability to function in saline water presents the exciting prospect of using seawater for hydrogen production, potentially reducing costs associated with desalination processes. The collaboration between KRISS, Seoul National University, and the Korea Institute of Materials Science underscores the significance of this achievement in advancing chemical engineering. Published in a respected journal, the research highlights the catalyst's potential to accelerate the commercialization of green hydrogen technology. With the promise of sustainable hydrogen production powered by renewable energy sources, this catalyst represents a crucial step towards a greener, more sustainable energy future.
