One‐Pot Synthesis of CeO2‐Supported Pd–Cu‐Alloy Nanocubes with High Catalytic Activity

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. 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.
