Abstract: In this study, a novel heterogeneous and reusable nanostructure catalyst was synthesized through the immobilization of bimetallic Cu–Fe mixed oxides on silica-layered magnetite. The prepared nanomagnetic Fe3O4@SiO2@CuO–Fe2O3 was characterized using Fourier-transform infrared spectroscopy, scanning electron… read more here.
