WebbA G-band at around 1575cm −1 in the Raman spectra represents the sp 2-hybridized carbon structure of GO, while a D-band at around 1355cm −1 appears when the carbon structure exhibits small defects or edges. The intensity ratio (intensity of the D-band/intensity of the G-band, ID/IG) represents the structural integrity of GO. WebbRaman spectra showed the increase in the disorder parameter (ID/IG) of Ag-rGO after electron irradiation due to the formation of large number of small sp2 domains. Moreover, as an application of the synthesized Ag-rGO sample showed an enhanced photo-catalytic degradation of methylene blue compared to graphene oxide, rGO and AgNPs under …
