New stable water-splitting catalyst doesn’t require expensive iridium
Green Car Congress
OCTOBER 22, 2022
Researchers have developed a nickel-stabilized, ruthenium dioxide (Ni-RuO 2 ) anode catalyst for proton exchange membrane (PEM) water electrolysis. The ruthenium—a more abundant precious metal—serves as a promising alternative to the more rare and expensive iridium—currently the practical anode catalyst for electrolysis. The Ni-RuO 2 catalyst shows high activity and durability in acidic OER for PEM water electrolysis.
