Iron-based catalyst achieves near-perfect efficiency for water oxidation, offering sustainable hydrogen production

A newly developed pentanuclear iron complex (Fe5-PCz(ClO4)3) can offer an efficient, stable, and cost-effective solution for water oxidation. By electrochemically polymerizing the complex, researchers from the Institute of Science Tokyo obtained a polymer-based catalyst, poly-Fe5-PCz, and achieved water oxidation with up to 99% Faradaic efficiency and exceptional stability, even under rigorous conditions.
