Billions of precious metal catalysts are used worldwide to produce chemicals, generate electricity, or purify the air.
However, the resources required for these applications are expensive and limited.
To optimize resource utilization, catalysts based on single metal atoms have been developed.
Research teams have demonstrated that precious metal atoms can aggregate to form clusters under specific conditions.
These clusters are more reactive than single atoms and therefore offer superior performance in exhaust gas removal.

They typically consist of tiny particles of an active ingredient (such as a precious metal) coated on a support material.
These so-called nanoparticles are composed of thousands of metal atoms, but only the outer atoms are active in the reaction, while the majority remain unused.
The structure of such catalysts can be altered by changing the operating conditions.
For example, the exhaust system of a car can reach high temperatures during long highway journeys.

The interaction between the precious metal and the support can lead to the formation of single atoms—isolated metal atoms on the support.
Because all atoms can theoretically participate in the reaction, this single-atom catalyst promises extremely high utilization of precious metal components.
However, using highly specialized spectroscopy and theoretical calculations, they successfully induced the formation of single atoms and thoroughly examined their structures during the reaction.
These methods were applied to this type of catalyst for the first time.
The team successfully explained why platinum atoms are typically less active and must react with oxygen in the catalyst. To achieve this, both components must be present.
