Abstract

An atomic-scale engineered octopod nanoframe architecture (OFA) consisting of 3D catalytic surfaces and beneficial high-index facets is developed via a facile one-pot synthesis method. Based on the reliable recipe and general method, various complex nanoframe architectures are developed. Specially, the PtCu OFAs exhibit exceptional activity and stability for the oxygen reduction reaction and can be easily scaled up to high-quality.

Keywords: atomic-scale engineering; catalysis; high-index facets; octopod nanoframes; oxygen reduction reaction.
