Recently, graphene oxide and its products have been recognized as a common nanostructure material due to many applications. The synthesis of graphene oxide besides the extract of Juglans Nigra leaves caused to fabrication of Ag-shaped nanocomposites. The extract was added to 15 and 25 mg of AgNO3 and MQ water and then the obtained mixture was refluxed through agitating a heater stirrer at 100 ? for 3 h (i.e., 15Ag/GO-J and 25Ag/GO-J) or sonicated at room temperature for 30 min (*15Ag/GO-J). A range of characterizations including FE-SEM, EDS, XRD, and FT-IR proved the fabrication of cubic Ag nanoparticles immobilized in graphene oxide nanosheets. The Ag-shaped nanocomposites proved to be active photo-nanocatalysts for removing methyl blue (MB) and methyl orange (MO) from wastewater. MB and MO were degraded in the presence of UV or Vis radiation by *15Ag/GO-J, 15Ag/GO-J, and 25Ag/GO-J as photo-nanocatalysts. The results confirmed the nearly full conversion of MB (~ 97%) from wastewater in the presence of Vis radiation by *15Ag/GO-J photo-nanocatalysts even at the short reaction time (about 15 min).
