Chemists uncover the true active surface of nickel catalysts
Researchers at Ulm University have revealed that the true active surface of nickel catalysts used in alkaline water electrolysis is nickel dioxide (NiO₂), refuting the long-held assumption that it was nickel oxyhydroxide (NiOOH). This discovery marks a significant step forward in understanding hydrogen production technologies, providing vital insights that could optimize cost-effective, climate-neutral energy solutions.
