Resumen

This study presents a novel synthesis method for the production of reduced-graphene-oxide functionalized with gold nanoparticles (rGO/Au-NPs) at ambient temperature. Both were obtained simultaneously using sucrose and chloroauric acid as precursors in the formation of the nanocomposite, and ascorbic acid as the reducing and stabilizing agent. Transmission electron microscopy (TEM) showed gold nanoparticles of 15–30 nm interacting with rGO laminates. Raman spectroscopy showed bands D and G centered at 1334 cm−1 and 1577 cm−1, respectively. The optical absorption analysis presented two bands centered at 522 nm and 260 nm, similar to the results reported in literature for Au-NPs and rGO.
