摘要：
A novel protection-reduction technique is developed for the preparation of silver nanoparticles, nanorods and wheatear-like supramolecular nanostructures at room temperature using silver potassium cyanide [KAg(CN)2] as a silver source, vitamin C (Vc) as a reducing agent and polyvinylpyrrolidone (PVP) as a protecting agent. The concentration of KAg(CN)2, the mole ratios of PVP/Vc and KAg(CN)2/Vc have significant effects on the formation and growth of these novel nanostructures. This method may be extended to prepare novel nanostructures of other metals.
