Magnetic Au-Ag-γ-Fe<sub>2</sub>O<sub>3</sub>/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-&#947;-Fe<sub>2</sub>O<sub>3</sub>/rGO nanocomposites. The impact of the preparation method (the intensity of reductant) on the catalytic performance was investigated. The nanocomposite...
