摘要

This Letter describes a new approach for synthesis of flower-like silver nanostructured particles by using a polystyrene (PS) template. Ag nanoparticles (NPs) were prepared successively by the addition of AgNO3 aqueous solution to the dispersion, adsorption of Ag+ ions on the surfaces of a functional PS template and then the reduction of Ag+ ions to flower-like silver NPs by aqueous hydrazine hydr...
