Aiming to design and develop efficient ethanol electrooxidation reaction (EOR) catalysts, a new Pd-Au-P ternary nanoalloy catalyst (denoted as Pd₄Au₁-P/PDIL-CNTs) comprised of the ultrafine ternary alloyed nanoparticles of Pd₄Au₁-P (∼2.3 nm) uniformly anchored on ionic liquids derived from 3,4,9,10-perylene tetracarboxylic acid noncovalent functionalized carbon nanotubes (PDIL-CNTs) was fabricated through a facile surfactant-free wet chemical technique. Systematic characterization confirmed the formation of the Pd₄Au₁-Pd ternary nanoalloy and different electronic effects of the two alloying elements (Au and P) on Pd. Impressively, the Pd₄Au₁-P/PDIL-CNTs possessed promoted electrocatalytic performance, accelerated kinetics and enhanced stability than other tested catalysts toward EOR in alkaline medium, primarily owing to the synergistic effect of PDIL-CNTs, P, Au and Pd. Furthermore, a possible synergistic mechanism of PDIL-CNTs, P, Au and Pd for EOR is also proposed. Consequently, the newly-designed ternary alloyed catalyst has great promise in constructing high-performance portable systems for advanced applications.

为了设计和开发有效的乙醇电氧化反应（EOR）催化剂，一种新型Pd-Au-P三元纳米合金催化剂（表示为Pd ₄ Au ₁ -P / PDIL-CNTs）由Pd ₄ Au ₁的超细三元合金纳米颗粒组成通过一种简便的无表面活性剂湿化学技术，制备了均匀锚固在3,4,9,10-per四羧酸非共价官能化碳纳米管（PDIL-CNT）衍生的离子液体上的-P（〜2.3 nm）。系统表征证实了Pd ₄ Au ₁ -Pd三元纳米合金的形成以及两种合金元素（Au和P）对Pd的不同电子效应。令人印象深刻的是Pd ₄ Au ₁-P / PDIL-CNT在碱性介质中比其他测试催化剂对EOR具有增强的电催化性能，加速的动力学和增强的稳定性，这主要归因于PDIL-CNT，P，Au和Pd的协同作用。此外，还提出了PDIL-CNT，P，Au和Pd用于EOR的可能的协同机制。因此，新设计的三元合金催化剂在构建用于高级应用的高性能便携式系统方面具有广阔的前景。
