Electrochemical water splitting is a process in which water molecules are split into hydrogen and oxygen gases by applying an electrical potential across two electrodes, with the hydrogen evolution reaction (HER) occurring at the cathode and the oxygen evolution reaction at the anode.[6] It is a cornerstone technology for producing green hydrogen when powered by renewable electricity, and its efficiency strongly depends on the performance of the electrocatalysts used at each electrode.[6]

Water-soluble macromolecule with enhanced redox activity for temporary electron storage.

These are nanoscale catalyst particles composed initially of alloyed platinum and nickel atoms that can reorganize under stimulus into hybrid structures with one platinum-rich metallic half and one nickel oxide half, joined at an atomically defined interface highly active for the hydrogen evolution reaction in water electrolysis.[1][2] The material aims to provide record‑level hydrogen production performance while minimizing platinum usage by leveraging cooperative interactions between Pt and NiO at the interface.[1][2][6]
