The Science study found the particles were four times more active than pure ruthenium and remained stable after 12 hours at 900C.
Using ruthenium with iron, cobalt, nickel and copper, the team achieved unusually uniform nanocrystals, with copper guiding an ordered onion-like structure that resisted sintering.
The work could cut reliance on scarce ruthenium and aid hydrogen-energy infrastructure, while BASF is testing the catalysts under more realistic industrial conditions.
Could this five-metal catalyst finally slash the production costs hindering the global green hydrogen economy?
Beyond heat resistance, what hidden vulnerabilities could derail these 'super catalysts' in real-world industrial use?
If complexity creates order, what other 'impossible' materials can now be designed using this paradoxical new blueprint?
Five-Metal Nanocrystal Catalyst Achieves Fourfold Increase in Ammonia Decomposition Rate with Exceptional Stability at 900°C
Overview
On May 7, 2026, researchers from Stanford, KAIST, and BASF announced a breakthrough five-metal nanocrystal catalyst featuring a unique self-organizing mechanism. This design forms an onion-like layered structure with a ruthenium-copper heterodimer core, surrounded by cobalt, nickel, and iron layers. This architecture prevents sintering, optimizes active site exposure, and enables synergistic metal interactions, resulting in a fourfold increase in ammonia decomposition rates and exceptional stability at 900°C. By reducing reliance on costly ruthenium and advancing toward industrial-scale testing, this catalyst promises efficient hydrogen release from ammonia, a key step for a sustainable hydrogen economy. Future work focuses on scalable synthesis and broader catalytic applications.
