Shape-tailoring of CuPd nanocrystals for enhancement of electro-catalytic activity in oxygen reduction reaction

Abstract

CuPd nanocrystals with different shapes including cubes, truncated cubes, cuboctahedra, irregular polyhedra, and tetrapods, have been synthesized by the modification of reactant concentrations. The electrocatalytic activity of the CuPd nanocubes toward the oxygen reduction reaction (ORR) is the higher than the commercial Pt/C catalyst.
