Noble Metal-Nonstoichiometric Copper Chalcogenide Dual-Plasmonic Hybrid Heteronanostructures with Tunable Optical Properties and Optimized Photocatalytic Activities

Multicomponent plasmonic nanoparticles, especially structurally well-defined noble metal-nonstoichiometric copper chalcogenide (p-type) dual plasmonic hybrid hetero-nanostructures, have emerged as an intriguing platform of superstructures due to their synergistically reinforced optical properties. The integration of two intrinsically dissimilar plasmonic constituents in one nano-entity empowers us to explore many new-yet-unexpected features, holding tremendous potential for plasmon-mediated energy transfer, plasmon-enhanced photocatalysis, and plasmon-related photothermal and photodynamic theranostics. Over the past decades, the research on dual plasmonic nanostructures has been burgeoning and much progress has been made with respect to the synthesis of a wide variety of dual plasmonic nanostructures with distinctive sizes, shapes or mophologies. Several dual-plasmonic hybrid heteronanostructures with geometrically tunable optical properties and tailored photocatalytic performance synthesized and characterized in our lab will be discussed in this symposium.
