Preparação e caracterização do nanocompósito baseado em óxido de grafeno reduzido/hexacianoferrato de óxido de rutênio e aplicação como sensor eletroquímico
Abstract:The preparation of a nanocomposite based on reduced graphene oxide and ruthenium oxide hexacyanoferrate (rGO/RuOHCF) nanoparticles was performed by cyclic voltammetry. Control-materials were prepared analogously for comparison. Electrochemical tests revealed a synergic effect between the rGO sheets and RuOHCF nanoparticles due to current intensity increasing and higher stability during 50 voltammetric scans comparing to RuOHCF film. The results were more pronounced in acidic media (pH= 1.5), which was used for… Show more
