A new kind of multifunctional Co0.85Se-Fe3O4 nanocomposites is synthesized by loading Fe3O4 nanoparticles (NPs) with a size of about 5 nm on the surface of Co0.85Se nanosheets under hydrothermal conditions without using any surfactant or structure-directing agents. The Co0.85Se-Fe3O4 nanocomposite exhibits remarkable catalytic performance for hydrogenation of p-nitrophenol (4-NP) at room temperature and good adsorption behavior for methylene blue trihydrate in water. This nanocomposite also shows a high specific surface area and magnetic separation capability for recyclable utilization. The enhanced performances both in catalysis and adsorption are better than either individual component of Co0.85Se nanosheets or Fe3O4 nanoparticles, demonstrating the possibility for designing new multifunctional nanocomposites with improved performances for catalysis, adsorbents, and other applications.
