    摘要: Methods for producing multifaceted nanoparticles and uses thereof are disclosed. One method for producing multifaceted nanoparticles can include obtaining a template that includes a substrate and a polymer brush having a plurality of polymers each attached by a first end to the substrate and each having a free opposing second end located opposite the first end; contacting the polymer brush with a solution that includes a nanoparticle precursor material; and forming, from the precursor material and the functional groups located on the second end of the plurality of polymers, multifaceted nanoparticles. The second ends of the polymer chains are functionalized with functional groups that have an affinity for the facets of the multifaceted nanoparticles.

    摘要: A variety of polyhedral nanocages are provided having a hollow interior, ultrathin walls, and well-defined facets of metal atoms. The nanocages can include a variety of precious metals such as Pt, Au, Ru, Rh, or Ir. The metal atoms can take a face-centered cubic structure with {111} facets on the surface. The walls can be thin, sometimes less than 1 nm in thickness or only a few atomic layers in thickness. The nanocages can provide for efficient uses of valuable precious metals, among other things, in catalysis. For example, catalysts are provided exhibiting high mass activities in oxygen reduction reactions. Methods of making and methods of using the nanocages and catalysts are also provided.
