▎ 摘  要

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 nanoparticle-graphene interface. Probing by reactive gases showed that the nanoparticles provide interaction sites, inducing the sensitivity to H2S and improving the sensitivity to NO2.
