Dethroning Electrocatalysts for Hydrogen Production with Inexpensive Alternative Material

Scientists at Tokyo Institute of Technology (Tokyo Tech) discover a new electrocatalyst for the oxygen evolution reaction (OER) in electrochemical water splitting: CaFe2O4. This inexpensive, non-toxic, and easy-to-synthesize material outperforms other bimetallic OER electrocatalysts and even surpasses the benchmark set by iridium oxide, paving the way to accessible hydrogen generation for upcoming hydrogen societies.
