Traditional modes of catalyst deactivation such as Ostwald ripening and particle migration and coalescence eventually lead to sintering and particle growth. Now, Cargnello and colleagues identify loading-dependent particle decomposition into single atoms as an important deactivation mechanism during methane combustion on colloidal Pd nanocrystals.
