A layer-by-layer core-shell strategy to assemble stable and magnetically recyclable gold nanocatalysts was reported here. Under the mild conditions applied in the synthesis, functionalities from individual components are well maintained, exposed and integrated together. As-prepared nanocomposites, comprising of a magnetite core and catalytically active gold nanoparticles imbedded in a porous titania shell, exhibit conspicuous performance in both the reduction of 4-nitrophenol and the epoxidation of styrene. While the high-magnetization superparamagnetic core endows the composites with outstanding recyclability in catalysis applications, the imbedding structure of gold nanoparticles in porous titania shell enables to prevent catalytic nanoparticles from sintering and also create the synergetic effect between gold nanoparticle and titania for catalysis.

Keywords:Inorganic Chemistry; Core-shell nanocomposites; Gold nanocatalysts; Epoxidation; Recyclability
