Catalysts containing 3 or 4 atoms exposed at the surface
Researchers have begun creating catalysts containing just three or four atoms, known as ensembles, that exhibit properties more like a single atom. The clusters are very small, and the atoms are all exposed at the surface. Research findings suggest that catalysts made of just a few atoms promise greater efficiency in environmental remediation applications like water treatment.
