Abstract

In this paper, we present the design and implementation of a type of yolk-like Fe3O4@C–Au@void@TiO2–Pd hierarchical microspheres with visible light-assisted enhanced photocatalytic degradation of dye and rapid magnetic separation. The resulting composite microspheres exhibited yolk-like hierarchical structures with a 236.3 m2 g−1 surface area and a high-saturation magnetization of 31.5 emu g−1. As an example of applications, the photodegradation of Rhodamine B (RhB) in the presence of NaBH4 was investigated under simulated sunlight irradiation. The results show that the photocatalytic activity of the yolk-like Fe3O4@C–Au@void@TiO2–Pd microcomposites in the RhB photodegradation is higher than the Fe3O4@C–Au@void@TiO2 and Fe3O4@C@TiO2 microcomposites, as they can degrade RhB with 40 min of irradiation time. In addition, by magnetic separation, the as-prepared yolk-like Fe3O4@C–Au@void@TiO2–Pd hierarchical microcomposites can be completely separated and reused for four times.
