dc.description.abstract | In this paper, we detail improvements in the sensing properties of reduced graphene oxide (AGO), which were achieved through functionalization. The functionalization process utilizes graphene oxide suspensions, generating nanoparticles on the AGO surface mainly comprised of Ni(OH)(2) phase. Raman spectra indicate that functionalization increases the degree of disorder in RGOs. NO2 gas sensing tests reveal an approximate increase of 154% in the sensor response of the RGOs after functionalization. Possible mechanisms for improving sensing responses via functionalization are discussed. The enhancement is due to the spillover effect, to the increase of the sensor surface by the catalytic particles, to the reduction of AGO conduction volume through the generation of depletion region, and to the resistance modulation of the heterojunctions. | en_US |
