A versatile strategy to construct multifunctional metal oxide@cyanometallate-based coordination polymer heterostructures.

We have developed one versatile spatially confined self-assembly strategy to integrate cyanometallate-based coordination polymers with functional metal oxides into well-defined core@shell heterostructures. The structure, composition, size and morphology of the heterostructures could be facilely controlled. The obtained Fe3O4@Prussian blue heterostructure was evaluated as an appealing multifunctional thermal ablation agent exhibiting response to both magnetic field and light irradiation.

Three-dimensionalization of ultrathin nanosheets in a two-dimensional nano-reactor: macroporous CuO microstructures with enhanced cycling performance.

Three-dimensional (3D) macroporous CuO structures composed of ultrathin nanosheets were successfully synthesized by employing a liquid-liquid interface as a two-dimensional (2D) nano-reactor. The macroporous structure helped CuO to retain the exposed surface during reactions, thus significantly enhancing the long term cycling performance both in photocatalysis and lithium ion batteries.

Monocrystalline mesoporous metal oxide with perovskite structure: a facile solid-state transformation of a coordination polymer.

Monocrystalline mesoporous BiFeO3 crystals were obtained via a multi-step single-crystal to single-crystal transformation of a coordination polymer, Bi[Fe(CN)6]·4H2O. This unique transformation process significantly decreased the crystallization temperature of perovskite oxide without losing high crystallinity.
