Ag nanoplates have received intensive attention due to their potential applications in molecular detection, optoelectronics and sensing etc. At present, many methods have been available for generating Ag nanoplate with different sizes and shapes. Such methods and modified versions thereof, usually involved the use of citrate as a capping agent, which can selectively bind to {111} facets maintaining a plate-like shape, or the use of weak reducing agents to achieve kinetic control for generating a planar structure. Here we reported a novel 2D oriented attachment growth of Ag nanoplates using polyethylene glycol (PEG) as a solvent as well as a reducing agent, in the presence of PVP. In our modified polyol method, the nucleation and seed stage occurred in the aqueous solution, and the 2D oriented attachment growth stage occurred in the PEG environment through evaporation of water.
