Porous carbon-supported PtPdCu alloy heterostructures with a three-dimensional spatial network for efficient ethanol electro-oxidation.

Rationalizing efficient and economical electrocatalysts for ethanol electro-oxidation (EOR) is crucial for the development of sustainable energy sources. Herein, porous carbon-supported PtPdCu ternary alloy heterostructures (PtPdCu/C,  :  :  = atomic ratio) were constructed using Cu-BTC as the precursor. Benefiting from the advantages of its three-dimensional spatial network structure, flexible ternary alloy composition and strong metal-support interaction, the as-designed PtPdCu/C catalyst presents impressive EOR performance.
