dc.description.abstract | The phase control, hierarchical architecturing and hybridization of iron oxide is important for achieving multifunctional capability for many practical applications. Herein, hierarchically structured reduced graphene oxide (hrGO)/alpha-Fe2O3 and gamma-Fe3O4 nanobox hybrids (hrGO/alpha-Fe and hrGO/gamma-Fe NBhs) are synthesized via a one-pot, hydrothermal process and their functionality controlled by the crystalline phases is adapted for energy storage and photocatalysis. The three-dimensionally (3D) macroporous structure of hrGO/alpha-Fe NBhs is constructed, while alpha-Fe2O3 nanoboxes (NBs) in a proximate contact with the hrGO surface are simultaneously grown during a hydrothermal treatment. The discrete alpha-Fe2O3 NBs are uniformly distributed on the surface of the hrGO/alpha-Fe and confined in the 3D architecture, thereby inhibiting the restacking of rGO. After the subsequent phase transition into gamma-Fe3O4, the hierarchical structure and the uniform distribution of NBs are preserved. Despite lower initial capacity, the hrGO/alpha-Fe NBhs show better rate and cyclic performances than those of commercial rGO/alpha-Fe due to the uniform distribution of discrete alpha-Fe2O3 NBs and electronic conductivity, macroporosity, and buffering effect of the hrGO for lithium ion battery anodes. Moreover, the catalytic activity and kinetics of hrGO/gamma-Fe NBhs are enhanced for photo-Fenton reaction because of the uniform distribution of discrete gamma-Fe3O4 NBs on the 3D hierarchical architecture. | - |
