<strong><em><span>Electrodeposited Pd and PdNi coating samples were tested for ethanol oxidation reaction (EOR) in alkaline solution using cyclic voltammetry (CV), chronoamperometric (CA) and quasi steady state measurements. All alloy samples showed higher current densities for the EOR than pure Pd coating. The current density increased with increasing the amount of Pd in the PdNi coating and the most active one was found to be Pd<sub>0.74</sub>Ni<sub>0.26</sub>. Based on CA measurements a pseudo-steady state is achieved after 1500 s showing that Pd<sub>0.74</sub>Ni<sub>0.26</sub> is more efficient and poisoning more tolerant than other investigated coatings. Upon the end of the current-time transient, the investigated catalysts were subjected to the potential cycling showing the ability to recover activity loss implying the surface composition stability of  binary coatings</span></em></strong>

General Method

Pt-based multimetallic nanorings with a hollow structure are attractive as advanced catalysts due to their fantastic structure feature. However, the general method for the synthesis of such unique nanostructures is still lack. Here we report the synthesis of Pd@PtM (M = Rh, Ni, Pd, Cu) multimetallic nanorings by selective epitaxial growth of Pt alloyed shells on the periphery of Pd nanoplates in combination with oxidative etching of partial Pd in the interior. In situ generation of CO and benzoic acid arising from interfacial catalytic reactions between Pd nanoplates and benzaldehyde are critical to achieve high-quality Pt-based multimetallic nanorings. Specifically, the in-situ generated CO promotes the formation of Pt alloyed shells and their epitaxial growth on Pd nanoplates. In addition, the as-formed benzoic acid and residual oxygen are responsible for selective oxidative etching of partial Pd in the interior. When evaluated as electrocatalysts, the Pd@PtRh nanorings exhibit remarkably enhanced activity and stability for ethanol oxidation reaction (EOR) compared to the Pd@PtRh nanoplates and commercial Pt/C due to their hollow nanostructures.
