Magnetic Au-Ag-γ-Fe(2)O(3)/rGO Nanocomposites as an Efficient Catalyst for the Reduction of 4-Nitrophenol

In this paper, a facile route has been developed to prepare magnetic trimetallic Au-Ag-γ-Fe(2)O(3)/rGO nanocomposites. The impact of the preparation method (the intensity of reductant) on the catalytic performance was investigated. The nanocomposites were characterized by transmission electron micro...

Sumario:In this paper, a facile route has been developed to prepare magnetic trimetallic Au-Ag-γ-Fe(2)O(3)/rGO nanocomposites. The impact of the preparation method (the intensity of reductant) on the catalytic performance was investigated. The nanocomposites were characterized by transmission electron microscopy (TEM), X-ray diffraction (XRD) and X-ray photoelectron spectroscopy (XPS). The prepared nanocomposites show fine catalytic activity towards the reduction reaction of 4-nitrophenol (4-NP). The nanocomposites also have superparamagnetism at room temperature, which can be easily separated from the reaction systems by applying an external magnetic field.
