摘要：

An aqueous dispersion was prepared by attaching positively charged gold nanoparticles to the surface of poly-sodium-p-styrenesulfonate-modified Fe3O4 nanoparticles. The Fe3O4@positively charged gold nanoparticles offer high monodispersion, stability against aggregation, and high magnetization with uniform size. The Fe3O4@positively charged gold nanoparticles were efficient and recyclable catalysts due to the formation of a positively charged gold layer on the surface of Fe3O4 nanoparticles and were stable in aqueous solution for over forty-eight hours and hence may have a broad range of applications.
