Visible-light-driven trimetallic Pt-Ag-Ni alloy nanoparticles for efficient nanoelectrocatalytic oxidation of alcohols

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 Pt2Ag1 Ni-1 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.
