Graphene oxide (GO) nanocomposites reduced were synthesized by hydrothermal methods and reduction methods. Commonly, are functionalized with gold, silver and other metals to give it even more novel optoelectronic properties. We synthetized a composite by reduction of AgNO3 with sodium citrate in present of GO under vigorous string and 90 °C of temperature. Finally, the nanocomposite, AgNPs@GO which could be a new substrate for SERS.
