New five-metal nanocrystal designed for industrial hydrogen applications

Stanford and KAIST researchers built a uniform five-metal nanocrystal catalyst from ruthenium, iron, cobalt, nickel, and copper.

The particle self-organized into an onion-like structure and outperformed standard ruthenium catalysts in ammonia decomposition.

It ran about four times faster while remaining stable at very high temperatures.

The breakthrough could help make hydrogen transport and conversion more efficient and lower energy costs.
