The oil/waterinterfacial assembly strategy provides a powerful bottom-up approach for the
nanofilm fabrication due to low cost and low environmental impact [1]. Most
importantadvantages of this assembly strategy are the significant simplicity and universality
found in almost all of the related low dimensional nanostructures. Recently, this techniquehas
been used for the preparation of metal, semiconductor and oxide nanocrystals [2]. The method
used to prepare thin films at the organic-aqueous interface involves dissolving the relevant
precursor in the organic layer and injecting an appropriate reagent in the aqueous
layer.Graphene oxide (GO) is widely usedas excellent carbon support for catalysts to achieve
the desired activity and stability. It has been reported that graphene/GO-supported metal or
metal oxide nanoparticles (NPs) could improve the performance of catalysts in the different
ofreaction [3].
In this work, PdCuFe/RGO thin film was synthesized by the reduction of [PdCl2(cod)],
[Cu(acac)2] and [Fe(acac)3] complexes as palladium, copper and iron precursors at the
toluene-water interface. The nanohybrid was characterized by X-ray diffraction (XRD),
energy-dispersive analysis of X-ray (EDAX) and Transmissionelectron microscopy (TEM).
Then we investigated the catalytic activityproperty of this nanostructure in the reduction
reaction of p-nitrophenol.
