Dual-atom fuel cell catalysts break single-peak rule, exposing two optima

Researchers have uncovered a new principle that could accelerate the development of cheaper and more efficient fuel cells by revealing how dual-atom catalysts behave during a key energy conversion reaction. The study, led by researchers at Tohoku University, shows that these catalysts follow a previously unknown "dual-Sabatier optima" pattern, overturning long-standing assumptions in catalyst science. Details of the findings were published in Angewandte Chemie International Edition.
