The method of producing an expanded graphene structure intercalated with nanoparticles of metal in the form of a powder or foam

Patent number: 422453

Creators: Wiesław Stek, Dariusz Hreniak, Anna Łukowiak, Anna Wedzynska, Yuriy Gerasymchuk

The subject of the invention is a method of producing an expanded graphene structure intercalated with metal particles, where Brodie oxidised graphite is used as the substrate, which is reacted with a colloidal solution of nanometric metal particles or with a metal salt solution, where the metal ions are subjected to reduction under mild conditions, a partially reduced particle bed intercalated with graphite oxide metal nanoparticles is further heat-treated to form the final product in powder or foam form. Preferably, the nanosized inclusions of metallic particles include iron, cobalt, nickel, silver or gold.
