Synthesis and electrocatalytic properties of tetrahexahedral, polyhedral, and branched Pd@Au core-shell nanocrystals

Tetrahexahedral, polyhedral, and branched Pd@Au core-shell nanostructures were selectively produced by manipulating their growth thermodynamics and kinetics. The current density in the electrochemical oxidation of H2O2 and the electrochemiluminescence density of luminol-H2O2 systems at the tetrahexahedron modified electrode are 43.5 and 16.4 times that at the bulk Au electrode, respectively
