Researchers from Tokyo Metropolitan University have revealed how a catalyst in a promising chemical reaction for industry helps make ammonia, a major ingredient in fertilizer. Copper oxide is a key ...

(top) Proportion of copper (I) in copper oxide and copper (0) in metallic copper particles under different applied voltages. A more negative voltage correlates with the appearance of more Cu-Cu bonds.

Researchers discovered that copper oxide catalysts form metallic copper mid-reaction, triggering a dramatic boost in ammonia output. The insight offers a roadmap for designing cleaner, more efficient ...
