英文摘要Being able toprecisely control the morphologies of noble metallic nanostructures is of essential significance for promoting the surface-enhanced Raman scattering (SERS) effect. Herein, we demonstrate anovergrowth strategy forsynthesizingAu@M(M=Au, Ag, Pd, Pt) core–shell heterogeneous nanocrystals with an orientated structural evolution and highly improved properties by usingAu nanorods as seeds. With the same reaction condition system applied, we obtain four well-designed heterostructures with diverse shapes, including Au concave nanocuboids (Au CNs), Au@ Ag crystalizing face central cube nanopeanuts, Au@ Pd porous nanocuboids andAu@ Pt nanotrepangs. Subsequently, the exact overgrowth mechanism of theabove heterostructural building blocks is further analysed via the systematicoptimiziation ofa series of fabrications. Remarkably, the well-defined Au CNs and Au@ Ag nanopeanuts both exhibit highly promoted SERS activity. We expect to be able tosupply a facile strategy for thefabrication ofmultimetallic heterogeneous nanostructures, exploring the high SERS effect and catalytic activities.
