•Trimetallic Pt-Ag-Ni NPs have been successfully fabricated.•The Pt-Ag-Ni NPs can serve as a new class of advanced nanocatalysts.•SPR induce PtAgNi NPs display great enhancement in catalytic activity.•This work offers a feasible route for engineering desirable nanocatalysts. 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. [Display omitted]
