• for Ag–Pt and Ag–Rh compared to the monometallic constituents, and persisted at lower loading ratios and consecutive reduction cycles. The enhancement is attributed to the Rh and Pt nanoparticles forming antenna–reactor-type plasmonic catalysts with the Ag nanostructures. Keywords: Ag; antenna

• dissipation, the experiments concluded that charge carriers produced in the Pt shell via LSPR excitation from the Ag nanocube core could be utilized for surface chemistry. Similarly, Zhang et al. coined the term “antenna–reactor” photocatalysis by fabricating Al, surrounded by a thin layer of Al2O3, as a

• of the reduction can be directly observed via UV–vis absorption spectroscopy. Ag–Rh/Pt heterostructures exhibited a significantly increased catalytic activity compared to the constituents. The observed increase is attributed to the heterostructures forming antenna–reactor-type plasmonic catalysts
