In this work, we developed a simple method for obtaining composites of reduced graphene oxide (rGO) and Gold and Silver Nanoparticles (Au@AgNPs). Graphene oxide (GO) was prepared using Hummer´s method and then it was reduced using microwave radiation. Au and Ag nanoparticles were prepared by <i>in-situ</i> ablation method using a second harmonic of a Nd:YAG laser on the dispersion of GO. Finally, GO was reduced using microwave radiation and the nanocomposite Au@Ag@rGO was characterized terms of their morphological, structural, optical and catalytic properties.  For catalytic degradation, Eriochrome Black T (EBT) and Rodamina B (RB) dyes were used as a model compound. This study reveals efficient catalytic activity of Au@Ag@rGO, for the degradation of EBT and RB, about 90 and 95%, respectively
