| Abstract: | The current study suggests a convenient synthesis of in situ, ecofriendly and well-dispersed palladium nanoparticles with narrow and small dimension distributions on a graphene oxide (GO) surface using a Rosa canina fruit extract as a stabilizer and reducing agent without the addition of any other stabilizers or surfactants. The as-synthesized nanocatalyst (Pd NPs/RGO) was assessed with XRD, UV-vis, FE-SEM, EDS, TEM, ICP and WDX. The obtained heterogeneous nanocatalyst showed catalytic performance for reducing 4-nitrophenol (4-NP), rhodamine B (RhB) and methylene blue (MB) at ambient temperature in an ecofriendly medium. The catalyst was retained by centrifugation and reused several times with no considerable change in its catalytic performance.We suggests a convenient synthesis of in situ, ecofriendly and well-dispersed Pd nanoparticles with narrow and small dimension distributions on graphene oxide (GO) using Rosa canina extract as a reducing agent and as the only stabilizer. |
