In South Korea, new research from Chung Ang University presents a breakthrough in sustainable hydrogen production from seawater using chloride-resistant Ru nanocatalysts for direct electrolysis. The crystalline/amorphous Ru heterostructure exhibits 37× higher activity than commercial Pt catalysts in alkaline water electrolysis, enabling cost-effective hydrogen generation. By harnessing abundant oceanic resources, this approach enhances energy security, reduces fossil fuel dependence, accelerates decarbonization across various sectors, and paves the way for scalable, sustainable hydrogen infrastructure. The findings of their study were made available online in Advanced Functional Materials on August 7, 2025.
