Self-improvement process sees ruthenium clusters transition from amorphous shapes to truncated nanopyramids

Scanning transmission electron microscopy experiments have uncovered the structural changes a ruthenium catalyst undergoes that increase its activity during an ammonia cracking reaction. The findings could help researchers design better heterogenous catalysts in the future.
