One-pot synthesis of hierarchical concave tetrapod Pd nanocrystals and their electrocatalytic properties

Abstract

Well-defined Pd nanocrystals with both hierarchical pods and concave centers were synthesized by reducing Pd(acac)₂ with CO in the presence of polyvinylpyrrolidone and oleylamine in DMF. Oleylamine was responsible for the generation of the hierarchical concave tetrapod Pd nanostructures. The as-prepared novel Pd nanocrystals demonstrated highly enhanced electrocatalytic activity.
