Why is the Shape of Catalytic Nanoparticles Important?
The shape of catalytic nanoparticles can dictate the exposure of active sites. Different shapes expose different crystal facets, which have distinct atomic arrangements and electronic properties. These facets can exhibit different catalytic behaviors. For instance, Pt nanoparticles shaped as cubes might expose more (100) facets, which could be more active for certain reactions compared to (111) facets exposed by octahedral nanoparticles.
