A one-step and scalable production route to metal nanocatalyst supported polymer nanospheres via flash nanoprecipitation

Abstract

We report a scalable and continuous preparation route for metal nanoparticles (Au or Pt)@nanosphere polymer composites through flash nanoprecipitation (FNP). Uniform metal@nanosphere polymer composites with 2–3 nm metal colloids decorating the surface on the nanosphere are obtained with tunable overall particle size and metal nanoparticle arrangement. The obtained composites show high catalytic ability and stability in the reduction of p-nitrophenol.
