The Catalyst Kept Rebuilding the Useful Surface
A conductive NiCoFe alloy core supported reversible active phases during oxygen and urea oxidation.
Summary
A conductive NiCoFe alloy core supported reversible active phases during oxygen and urea oxidation.
In situ X-ray absorption measurements and density-functional calculations compared a layered hydroxide with a surface-reconstructed NiCoFe alloy. At higher current density and after cycling, the reconstructed catalyst required less potential and retained better turnover performance, including intermittent operation. The study attributes durability to a conductive core and more reversible surface phases; practical electrolyzer economics were not tested.
