AuxPdy-based Heterogeneous Nanocatalysts for Plasmon-mediated Enhanced Catalysis under Visible Light Irradiation
AuxPdy-based Heterogeneous Nanocatalysts for Plasmon-mediated Enhanced Catalysis under Visible Light Irradiation
The formation of hybrid plasmonic nanocatalysts made of Au nanoparticles (NPs) combined with catalytically active NPs has gained great attention owing to their interesting properties and efficient catalysis under visible light irradiation. However, the research on the combination of plasmonic metal NPs with unique support frameworks is still limited. In this report, the varying ratio of AuxPdy prepared by the extrusion method on the CuClP framework has been correlated to its optimized catalysis in the Suzuki-Miyaura coupling reaction in dark and under visible light irradiation. The prepared catalysts AuxPdy/CuClP were characterized by spectroscopic techniques to understand the structural and electronic modification with different metal ratios. The presence of bimetallic NPs on the surface was confirmed by HR-TEM measurements and [MCl4]n− species in the framework were validated by XPS, FT-EXAFS, DR UV-Vis-NIR, and Raman analysis. The obtained results display the superior catalytic performance and highest plasmonic enhancement factor over Au1Pd1/CuClP under visible light irradiation, which was facilely recycled and reused for several cycles. The hot-electron transfer mechanism has been discussed for enhanced catalysis in the plasmon-driven Suzuki−Miyaura coupling reaction. These results are highly significant in the rational design of new plasmonic photocatalysts combined with unique support materials.

Abstract
The formation of hybrid plasmonic nanocatalysts made of Au nanoparticles (NPs) combined with catalytically active NPs has gained great attention owing to their interesting properties and efficient catalysis under visible light irradiation. However, the research on the combination of plasmonic metal NPs with unique support frameworks is still limited. In this report, the varying ratio of AuxPdy prepared by the extrusion method on the CuClP framework has been correlated to its optimized catalysis in the Suzuki-Miyaura coupling reaction in dark and under visible light irradiation. The prepared catalysts AuxPdy/CuClP were characterized by spectroscopic techniques to understand the structural and electronic modification with different metal ratios. The presence of bimetallic NPs on the surface was confirmed by HR-TEM measurements and [MCl4]n− species in the framework were validated by XPS, FT-EXAFS, DR UV-Vis-NIR, and Raman analysis. The obtained results display the superior catalytic performance and highest plasmonic enhancement factor over Au1Pd1/CuClP under visible light irradiation, which was facilely recycled and reused for several cycles. The hot-electron transfer mechanism has been discussed for enhanced catalysis in the plasmon-driven Suzuki−Miyaura coupling reaction. These results are highly significant in the rational design of new plasmonic photocatalysts combined with unique support materials.
