In situ loading of gold nanoparticles on Fe3O4@SiO2 magnetic nanocomposites and their high catalytic activity

In this work, a facile approach was successfully developed for in situ catalyzing Au nanoparticles loaded on Fe 3 O 4 @SiO 2 magnetic nanospheres via Sn 2+ linkage and reduction. After the Fe 3 O 4 @SiO 2 MNPs were first prepared via a solgel process, only one step was needed to synthesize the Fe 3...
