Dethroning electro catalysts for hydrogen production with inexpensive alternative material

Scientists have discovered a new electro catalyst for the oxygen evolution reaction (OER) in electrochemical water splitting: CaFe2O4. This inexpensive, non-toxic, and easy-to-synthesize material outperforms other bimetallic OER electro catalysts and even surpasses the benchmark set by iridium oxide, paving the way to accessible hydrogen generation for upcoming hydrogen societies.
