Control over the Morphology and Plasmonic Properties of Rod-like Au-Pd Bimetallic Nanostructures

Abstract Bimetallic nanostructures are interesting materials for many applications ranging from plasmonics to catalysis. However, synthesizing bimetallic nanorods with good control over composition, morphology and maintaining an anisotropic shape is challenging. Here, we have shown a reproducible approach the synthesize core-shell within stabilizing mesoporous silica shell Au core Pd metal excellent their properties. Specifically, demonstrate that thickness of (rough/smooth) can be precisely tuned studied plasmonic properties resulting in detail. Our naturally extended different or more than two metals leading rod-shaped particles highly tunable interest use optical catalytic applications.
