On page 369 , R. Kydd et al. describe the creation of highly dispersed copper dimers (violet areas) on Ceria nanoparticles (green areas) via rapid flame‐spray pyrolysis. These as‐prepared copper dimers, in synergism with the oxygen vacancies in ceria, exhibit favourable electronic and catalytic interactions with incident CO molecules. Consequently, CO can be preferentially oxidised in H 2 streams at low temperatures.
