Description
Florian Maurer leads a 2026 team watching single platinum particles dissolve into lone atoms on ceria supports, then tying that decay to catalyst performance. Platinum on ceria anchors many clean air and chemical catalysts, yet under oxygen the particles can scatter into single atoms and lose punch. Using an electron microscope that works inside gas, the team timed the shrinking of individual particles on shaped ceria cubes.
Neighboring particles and flaws in the support slowed the scatter, while each particle lost volume at a steady rate regardless of starting size. Those atomic scale rates matched the fall in whole catalyst activity closely enough to forecast it. Maurer and the team call this a first step toward predicting catalyst life from particle kinetics.
