Liquid-liquid interface assisted synthesis of size- and thickness-controlled Ag nanoplates
- 化学化工－已发表论文 
Here we proposed a synthetic method of high-purity Ag nanoplates by the reduction of aqueous Ag+ ions at the aqueous-organic interface with the reductant ferrocene. We demonstrated that the as-prepared Ag nanoplates can be widely tunable from 600 nm to 7 mu m in size and from 10 to 35 nm in thickness, simply by adjusting the component of organic phase To our knowledge, there are few methods to tailor the size and the thickness of metal nanoplates in such a large range although many efforts have been made aiming to realize it. Our proposed synthetic strategy is rapid, template-free, seed-less, and high-yield, and could be applied to synthesize analogous two-dimensional nanostructures of other noble metals, such as Pt, Au, and Pd.
