High-efficiency adsorption of solar energy is a lofty goal and the pursuit of efficient photocatalyst is also one of the tough challenges. It's a growing interesting in the technology that is on the basis of surface plasma resonance (SPR) plasma resonance of the alloy nanoparticles (NPs). We herein successfully design a facile class of trimetallic Pt-Ag-Ni alloy NPs that combined the advantages of electronic effect, size and synergistic effect. Impressively, the Pt₂Ag₁Ni₁ NPs possess excellent electrocatalytic under visible light ethylene glycol oxidation reaction (EGOR) and glycerol oxidation reaction (GOR) with the mass activity founded to be: 7.99 and 4.88 A/mg, respectively. More significantly, SPR effect induces the optimal Pt-Ag-Ni NPs mass activity enhancement at 1.83 and 1.78 times higher under visible light than under environmental conditions. The design and SPR investigation of the trimetallic Pt-Ag-Ni alloy NPs in the research may provide a new approach for further development of high-performance nanocatalysts.

高效吸收太阳能是一个崇高的目标，追求高效的光催化剂也是艰巨的挑战之一。在基于合金纳米粒子（NPs）的表面等离子体共振（SPR）等离子体共振的技术中，它变得越来越有趣。我们在本文中成功设计了一种易用的三金属Pt-Ag-Ni合金NP，结合了电子效应，尺寸和协同效应的优点。令人印象深刻的是Pt ₂ Ag ₁ Ni ₁NP在可见光下具有出色的电催化乙二醇氧化反应（EGOR）和甘油氧化反应（GOR），质量活性分别为7.99和4.88 A / mg。更重要的是，SPR效应在可见光下诱导的Pt-Ag-Ni NPs最佳质量活性增强是在环境条件下的1.83倍和1.78倍。三金属Pt-Ag-Ni合金纳米颗粒的设计和SPR研究为进一步开发高性能纳米催化剂提供了新的途径。
