Completely green synthesis of rose-shaped Au nanostructures and their catalytic applications.

ABSTRACT: The importance of and demand for eco-friendly syntheses of metal nanocrystals are increasing. In this study, a novel protocol for the one-pot, template/seed-free, and completely green synthesis of rose-shaped Au nanostructures with unique three-dimensional hierarchical structures was developed. The synthesis of the nanostructures was carried out at room temperature using water as a reaction medium and an eco-friendly biopolymer (sodium salt of alginic acid (Na-alginate)) as a reducing agent. The morphologies of the Au nanostructures were controlled by adjusting the amount of capping ligand (polyvinylpyrrolidone (PVP)) in the reaction mixture, and a limited ligand protection (LLP) strategy was used to induce the formation of rose-shaped Au nanostructures. A formation mechanism for the rose-
