Pd-nanodot decorated MoS2 nanosheets as a highly efficient photocatalyst for the visible-light-induced Suzuki-Miyaura coupling reactionElectronic supplementary information (ESI) available. See DOI: 10.1039/c7ta08441b

In this work, we demonstrate that the incorporation of MoS 2 nanosheets with Pd nanodots is a promising way for promoting the visible-light-induced Suzuki-Miyaura C-C coupling reaction. The MoS 2 nanosheets decorated with Pd nanodots showed very high photocatalytic activity. The turnover frequency for the biphenyl product was >1600 h −1 even under sunlight illumination at room temperature. Mechanistic studies show that the high catalytic activity originated from the efficient electron-hole pair generation mechanism of MoS 2 under visible-light illumination instead of purely thermal effects. The incorporation of MoS 2 nanosheets with Pd nanodots is a promising way for promoting the visible-light-induced C-C coupling reaction.
