Abstract
Hierarchical dendritic nanostructures are rare and are usually synthesized by seed mediated epitaxial growth, which requires understanding of the symmetry-directed growth of the epitaxial layer on the facet-controlled nanocrysalline seed. Such a synthetic protocol involves alternation of the reaction conditions, and the one step synthesis of a hierarchical dendritic structure with exact mother to daughter crystal replication is a rarity. Herein we report a convenient one step synthesis of hierarchical dendritic Pt nanostructures with a concave Pt octahedron building unit by adopting reaction conditions in which Pt nanocrystal growth is extremely slow due to the reduction rate slowing the facet-etching process under an oxidizing atmosphere.
