| Abstract: | For the first time, copper nanoparticles (Cu NPs) superficially deposited on reduced graphene oxide (rGO) using Euphorbia cheiradenia Boiss leaf aqueous media. A beneficial series of analytical methods was used to characterise E. cheiradenia Boiss leaf extract and involved nanostructures. The Cu/rGO nanocomposite (NC) obtained from the conversion of Cu2+ ions to Cu NPs and GO to rGO undergoes the plant extract and used as a heterogeneous and reusable nanocatalyst for the destruction of 4‐nitrophenol, rhodamine B, methylene blue, methyl orange and congo red using sodium borohydride at ambient temperature. In addition, Cu/rGO NC has reusability for many times in the reduction reactions with no decreasing of its catalytic capability.Inspec keywords: catalysts, nanofabrication, nanocomposites, dyes, nanoparticles, reduction (chemical), copper, graphene compoundsOther keywords: phytosynthesis, organic dyes, reusable nanocatalyst, Euphorbia cheiradenia Boiss extract, 4‐nitrophenol, nanoparticles, graphene oxide, nanocomposites, methylene blue, methyl orange, congo red, sodium borohydride, catalytic capability, Cu‐CO |
