ICFO Researchers Discover Chromium's Role in Stabilizing Ruthenium for Water Electrolysis
Researchers at ICFO, in collaboration with institutions including the University of Bayreuth and the Catalan Institute of Nanoscience and Nanotechnology (ICN2), have identified chromium as a key element in stabilizing ruthenium for efficient water electrolysis. Ruthenium is commonly used in single-atom catalysts to accelerate the process of splitting water to produce green hydrogen. However, ruthenium on its own tends to over-oxidize and dissolve during operation, limiting its effectiveness. The study, published in Nature Materials, highlights that chromium acts as a stabilizing partner, preventing ruthenium from degrading. This discovery is crucial for improving the durability and performance of catalysts used in green hydrogen production, a vital component of future sustainable energy systems. The research team, led by ICFO professor F. Pelayo García de Arquer, included Tengyu Chen, Dr. Kaiwen Wang, Dr. Lu Xia, Dr. Wulyu Jiang, Dr. Linlin Yang, Dr. Kaiqi Zhao, Ranit Ram, Dr. Junmei Chen, Dr. Marinos Dimi...
