Abstract

Despite the great success of controlled synthesis of metal nanocrystals with various sizes and morphologies, an efficient one-pot approach to preparing well-organized three-dimensional (3D) structures with unique facets exposed remains a great challenge. Herein, we report a unique 3D nanoarchitecture for PdCu alloy, created by a simple chemical reduction method, in which nanosized octahedral PdCu nanocrystals are directly assembled into 3D super-branched structures. Detailed investigations of its electrocatalytic performance demonstrate that the as-prepared facet-controlled PdCu super-branched nanostructures possess higher activity towards the formic acid oxidation reaction in comparison to the commercially available Pd black catalyst.
