Abstract
Efficient bimetallic nanostructures, which show properties related to two sole metals, have empowered inventive applications in nanosciences and nanotechnology. Here, we construct bimetallic Au@Ag nano-urchins with controlled Au tips for Catalysis and SERS application. The proposed nano-urchins were synthesized via electrochemical and simple galvanic replacement reaction route. The construction of Ag nano-flowers via electrochemical deposition use as a shell and Au tips were grown via galvanic reaction route greatly enhanced SERS properties of crystal violet (CV) detection and stability of nanostructures. In a comparison of Ag flower-like structures, the catalysis properties of Au@Ag nano-urchins are extremely efficient in degrading p-nitrophenol. As a result, these bimetallic nano-urchins show great development in SERS substrate and efficient catalysts.
