▎ 摘　　要

Here, we report multi-component plasmonic core-shell nanodendrites (Pt@rGO-AuNPs) composed of nano-sized reduced graphene oxide coated gold nanoparticles as a multiple photo-system modality. The prepared Pt@rGO-AuNPs took 40, 60, and 75 min with the pseudo first-order rate constants 0.112 min(-1) 0.069 min(-1) and 0.048 min(-1) to completely degrade (>= 98%) methylene blue, methyl red, and methyl orange, respectively, at room temperature. Pt@rGO-AuNPs also showed a high photothermal effect (temperature >= 43 degrees C in 5 min, 808 nm laser, 6 W/cm(2)) and found to have robust morphology during recyclability for at least five cycles in both photocatalytic and photothermal processes.
