Multishelled Co3O4-Fe3O4 hollow spheres with even magnetic phase distribution: Synthesis, magnetic properties and their application in water treatment

摘要: Nowadays, despite the success evidenced in synthesis of hybrid materials, spherical materials are usually based on core-shell structures or alloy-like ensembles with homogenous distribution all components. For core-shells, performance a core part is hampered due to thick shell, and commonly have low surface area. Therefore, multishelled hollow both even phase well-ordered building blocks, may be better choice. In this paper, we developed new method successfully fabricate Co3O4-Fe3O4 above ideal structure. As-prepared products definite structural advantages. these not only exhibit excellent ability waste-water treatment applications, but also feasible for fast recyclable via simple magnetic separation. addition, they show interesting structure-dependent properties could serve as model material heterogeneous antiferromagnet/ferromagnet system without clear/sharp interfaces. Needless say, our newly synthetic approach extended toward other functional distribution.
