Abstract

Au@PdO_x with a PdO_x-rich shell and Au-rich core nested in Co₃O₄ nanorods exhibited enhanced catalytic performance in the reaction of methane catalytic combustion, compared to monometallic Pd or Au/Co₃O₄ nanorods as well as conventional PdAu/Co₃O₄ nanorods. The superior catalysis of Au@PdO_x/Co₃O₄ nanorods is mainly due to the architectural style of the PdO_x-rich shell and Au-rich core, which shows strong interaction of Pd, Au, and Co₃O₄.
