CHANGWON, South Korea — Korea Institute of Materials Science (KIMS), led by President Chuljin Choi, announced that a research team led by Dr. Dahee Park at the Hydrogen Energy Materials Research Center has successfully developed a high-performance catalyst that significantly enhances the oxygen evolution reaction (OER), a key process in alkaline water electrolysis. The team achieved this by partially substituting molybdenum oxide (MoOx) with iron (Fe), enabling simultaneous control of lattice structure and oxygen vacancies. The study presents a new catalyst design strategy that delivers performance and stability comparable to precious metal catalysts while utilizing low-cost materials.
