Helical PdPtAu nanowires bounded with high-index facets selectively switch the pathway of ethanol electrooxidation
Intensive studies have been devoted to the preparation of electrocatalysts with outstanding activity and stability for ethanol oxidation. However, the electrocatalytic efficiency is far from satisfactory for application due to the low catalytic activity and C1 product selectivity. Herein, helical Pd...

| description | Intensive studies have been devoted to the preparation of electrocatalysts with outstanding activity and stability for ethanol oxidation. However, the electrocatalytic efficiency is far from satisfactory for application due to the low catalytic activity and C1 product selectivity. Herein, helical PdPtAu nanowires (NWs) surrounded by high-index facets are fabricated for ethanol electrooxidation with enhanced C1 selectivity. Among the PdPtAu NWs with different Au contents, Pd
14
Pt
5
Au
2
NWs show the highest specific activity, which is 1.4, 5.5, and 7.3 times that of Pd
14
Pt

NWs, commercial Pt black, and Pd black, respectively. The Pd
14
Pt
5
Au
2
NWs have high anti-poisoning ability as confirmed by CO stripping and
in situ
FTIR spectra of CO adsorption.
In situ
FTIR investigations during the ethanol oxidation reveal that Pd
14
Pt

Au
2
NWs enhance the cleavage of the C-C bond, leading to a 3.3-fold increase in C1 selectivity (23.2%) compared with that of commercial Pd black (7.0%).
This work reports the fabrication of helical PdPtAu NWs bounded with high-index facets for ethanol electrooxidation. The NWs can enhance the catalytic performance, and the selectivity of C1 products on Pd
14
Pt
5
Au

NWs can be improved up to 23.2%. |
