Abstract:
Using gallic acid to reduce Ag[(NH3)2]+,the Fe3O4/Ag core-shell nanoparticles were synthesized by water co-precipitation method. The catalytic activity of the Fe3O4/Ag nanoparticles was investigated by the reduction of nitrobenzaldehyde with sodium borohydride. The result shows that the yield is nearly 97% when the temperature is 40 ℃ and concentration of the Fe3O4/Ag nanoparticles is 0.08%. Furthermore,the Fe3O4/Ag nanoparticles can be easily recovered from reaction system and their catalytic activity has not been obviously decreased after several recycles.
