Abstract: This paper is devoted to investigation of the effect of light in the visible spectral range on the activity of mono- (Au, Pd) and bimetallic (Au−Pd) catalysts. Electron microscopy data showed that nanoparticles with a core-shell structure are formed during the synthesis of a bimetallic catalyst. As a result of the testing of mono- and bimetallic samples in the Suzuki reaction between 4-bromoanisole and phenylboronic acid under optimum conditions, it was found that the activity of the bimetallic catalyst increases markedly when the light response is carried out by the occurrence of a local surface plasmon resonance, which is supposed to accelerate the stage oxidative addition of 4-bromoanisole to palladium.
Keywords: Suzuki cross-coupling reaction, gold, palladium, bimetallic catalyst, hypercrosslinked polystyrene, local surface plasmon resonance.
