摘要：

A novel magnetic double-shell Fe3O4@TiO2/Au@Pd@TiO2 microsphere composed of a Fe3O4 core and double TiO2 shells with Au and Pd nanoparticles encapsulated is created. The microsphere can be used as a highly efficient reusable catalyst with superior catalytic activity and stability and magnetic separable capability in reduction of 4-nitrophenol.
