Water electrolysis is a key technology to establish CO2-neutral hydrogen production. One of the key technological hurdles is the design of stable, active and affordable catalysts for the anodic oxygen evolution reaction (OER), which is one bottleneck of the hydrogen production process. Researchers from the Interface Science Department have now provided quantitative near-surface structural insights into oxygen-evolving CoOx(OH)y nanoparticles which are published in Nature Energy today.
