Abstract

original image

Cerium and nanocubes: CeO2-supported Pd–Cu-alloy nanocubes (Pd–Cu NCs/CeO2) with high content and good dispersion of the Pd–Cu NCs were prepared in high yields by heating a solution containing Pd, Cu, and Ce precursors (see figure). The prepared Pd–Cu NCs/CeO2 have excellent catalytic activity and stability toward formic acid electro-oxidation due to the synergism between the Pd–Cu-alloy catalysts and the CeO2 support.
