Description
Andrés López-García and eight colleagues coax, in 2026, tiny metal particles out of a cerium oxide support to crack ammonia into hydrogen. Particles grown from inside the support sit socketed and resist clumping at heat, yet ceria normally refuses to dissolve the needed metals. Adding gadolinium into the ceria lattice changed that, letting ruthenium and rhodium dissolve and later emerge as specks near three nanometers wide, some as mixed alloys.
The ruthenium version cracked ammonia steadily for 260 hours, beating a surface coated rival and ranking among the best at moderate heat. López-García and the team credit the dopant for widening which metals can be exsolved. They see the trick spreading to other catalyst families that need stable, fine particles.
