The chemical mechanism occurring at\nthe graphene-silver oxide interface is based on the reduction of silver oxide\ntriggered by graphene that acts as a shuttle of electrons and as a kind of catalyst\nin the deoxidation. A mechanism is formulated, combining elements of\nelectron transfer, role of defects in graphene, and electrochemical potentials\nof graphene, silver, and oxygen. Therefore, the formulated model represents\na step forward from the simple view of graphene as barrier to oxygen diffusion\nproposed so far in literature. Single layer graphene grown by chemical\nvapor deposition is transferred onto silver thin fi lms, a periodic silver fi shnet\nstructure fabricated by nanoimprint lithography, and onto silver nanoparticle\nensembles supporting a localized surface plasmon resonance in the visible\nrange. Through the study of these nanostructured graphene/Ag hybrids, the\neffectiveness of graphene in preventing and reducing oxidation of silver plasmonic\nstructures, keeping silver in a metallic state over months at air exposure,\nis demonstrated. The enhanced and stable plasmonic properties of the\nsilver-fi shnet/graphene hybrids are evaluated through their SERS response\nfor detecting benzyl mercaptane."@en ; prodottidellaricerca:prodottoDi modulo:ID2672 , istituto:CDS054 ; pubblicazioni:autoreCNR unitaDiPersonaleInterno:MATRICOLA11703 , unitaDiPersonaleInterno:MATRICOLA10662 , unitaDiPersonaleInterno:MATRICOLA794 , unitaDiPersonaleInterno:MATRICOLA2958 . ns11:ID58683 pubblicazioni:rivistaDi prodotto:ID274679 .
