Novel magnetic core/shell bimetallic Au/Cu nanoparticles (Fe3O4@SiO2-Au/Cu NPs) were prepared using SiO2-coated iron oxide (Fe3O4@SiO2) as a supported material. The magnetic Fe3O4 colloidal nanocrystal clusters (CNCs) as nano-core were modified with a silica coating for improvement stability and superficial area of the Au-Cu particles. The morphological structure and chemical composition of the Fe...
