Key Points

  • To explore the collective behavior of densely packed nanoparticles during catalytic reactions.
  • Operando electron microscopy was employed to analyze nanoparticle ensembles.
  • The study focused on CO oxidation reactions.
  • Densely packed nanoparticles were investigated for their interaction dynamics.
  • Identified catalytic hot-spots influencing CO oxidation.
  • Revealed how collective behavior affects reaction outcomes in nanoparticle ensembles.
  • Highlighted the significance of nanoparticle interactions in catalytic efficiency.

Abstract

Catalytic reactions over nanoparticle ensembles are often interpreted by intrinsic nanoparticle descriptors. However, the collective behavior that emerges as nanoparticles are densely packed remains rarely addressed. Here, we use operando...
