A new kind of multifunctional Co 0.85 Se‐Fe 3 O 4 nanocomposites is synthesized by loading Fe 3 O 4 nanoparticles (NPs) with a size of about 5 nm on the surface of Co 0.85 Se nanosheets under hydrothermal conditions without using any surfactant or structure‐directing agents. The Co 0.85 Se‐Fe 3 O 4 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 Co 0.85 Se nanosheets or Fe 3 O 4 nanoparticles, demonstrating the possibility for designing new multifunctional nanocomposites with improved performances for catalysis, adsorbents, and other applications.
