摘要: Bimetallic nanostructures show exciting potential as materials for effective catalysis. Magnetically recoverable bimetallic nanoparticles are promising catalysts chemical reactions. Here, Fe3O4@Pd and Fe3O4@Au–Pd hybrid were synthesized used catalysts. The morphology, composition, structure of the fully characterized by scanning transmission electron microscopy, energy dispersive spectroscopy, high angle annular dark-field TEM, X-ray powder diffraction, photoelectron etc. excellent catalytic activity towards reduction nitrophenols potassium hexacyanoferrate(III). In addition, magnetic heterogeneous can be easily recycled, showing good reusability; conversion higher than 99% was achieved after 6 cycles.
