| This study demonstrates a novel approach to synthesizing methods of core-shell nanoparticle assembly, using nanoparticle trapping at an interface and subsequent transfer onto a substrate for electrochemical ultrathin layer coating. The transferred nanoparticle array can have a tunable surface area depending on the number of transferred layers. Subsequent coating the surface with Pt-group metals with ultrathin film nature provides electrocatalytic activities with respect to a variety of chemical reactions, depending on the property of selected coating materials. The transferred 3-dimensional Au nanoparticle arrays act as a high surface area platform for the diversity of overlayer materials. The resulting 3-dimentional nanoparticle films could be utilized as a highly active electrocatalysis and Raman scattering substrate. The approach provides a versatile and convenient synthetic route to new nanoporous material with tailorable pore structure and material properties through bottom-up assembly. |
