Hybrid graphene–metal nanoparticle systems: electronic properties and gas interaction

Author affiliations

Abstract

Electrical properties of reduced graphene oxide (rGO) decorated with gold and silver nanoparticles were studied. Metal nanoparticles p-dope rGO through charge transfer which causes a potential drop at the metal nanoparticlegraphene interface. Probing by reactive gases showed that the nanoparticles provide interaction sites, inducing the sensitivity to H2S and improving the sensitivity to NO2.
