One-stone, two birds: Alloying effect and surface defects induced by Pt on Cu2-xSe nanowires to boost C-C bond cleavage for electrocatalytic ethanol oxidation

Hongcheng Peng et al.

Summary: Efficient C-C bond cleavage is crucial for ethanol electrooxidation. PtCu/Cu2-xSe nanowires exhibited high activity for ethanol and methanol oxidation due to the formation of PtCu alloys lowering the D-band level to promote hydroxyl species adsorption, and creating abundant defects with high density of low-coordinated atoms to boost reaction kinetics. The assembled direct ethanol fuel cells with PtCu/Cu2-xSe NWs as anode showed promising performance, providing a potential catalyst for C-C bond cleavage and an effective strategy to enhance electrocatalytic activity for ethanol/methanol oxidation.
