UlmNickel electrodes work as nickel dioxide, not oxyhydroxide as assumed.
Nickel is a cost-effective, robust catalyst for alkaline water electrolysis, a key route to climate-neutral hydrogen.
A research team at Ulm University determined the structure under reaction conditions and published it in Nature Catalysis.
The announcement describes no catalyst built on the finding yet.
How each outlet framed it
- Phys.org leans favorable
- stresses the decades-old NiOOH assumption is refuted, naming NiO₂ as the true active surface in Nature Catalysis
