Porous single-crystalline palladium nanoflowers with enriched {100} facets for highly enhanced ethanol oxidation

Abstract

Palladium porous single-crystalline nanoflowers (PSNFs) with enriched high catalytic activity {100} facets were synthesized using a mild and controllable seed mediated growth method. The growth mechanism of the Pd PSNFs was investigated using time dependent morphology evolution through TEM imaging. Due to the specific structure, Pd PSNFs show highly enhanced ethanol oxidation reaction (EOR) activity, high EOR anti-poisoning and stability, much better than Pd nanocubes, {111} facets dominated dendritic urchin-like Pd nanoparticles and Pd black.
