Nanotubular TiOxNy-Supported Ir Single Atoms and Clusters as Thin-Film Electrocatalysts for Oxygen Evolution in Acid Media
A recent Chemistry of Materials article, co-authored by researchers from the Department of Chemical and Pharmaceutical Sciences at the University of Trieste, the Department of Materials Chemistry (D10) and Department of Analytical Chemistry (D04) at National Institute of Chemistry Ljubljana, and Jožef Stefan Institute, explores renewable energy for hydrogen technologies. The article describes a novel approach for preparing thin-film electrode composites.
The researchers first prepared Ir in α-Ti solution using the triode sputtering method, then transformed it with anodic oxidation and heat treatments to create the desired TiOxNy–Ir film with Ir single atoms and clusters. This breakthrough offers valuable insights into designing catalysts with minimal content and high atom utilization efficiency of rare and expensive metals on the path to a carbon-free society.
