Abstract

The ORCID identification number(s) for the author(s) of this article can be found under https://doi.org/10.1002/adma.201803291.Hollow metal-organic framework (MOF) micro/nanostructures and their derivatives are attracting a great amount of research interest in recent years because their hierarchical porous structures not only provide abundant, easily accessed metal sites but also endow 3D channels for rapid mass transport. As a result, they demonstrate significant advantages in many applications including catalysis, gas sensors, batteries, supercapacitors, and so on. Nevertheless, studies on hollow MOFs and their derivatives are still at the beginning of this field, and the relationship between their structures and application performances is not yet reviewed comprehensively. Herein, the synthetic strategies and practical applications of hollow micro/nanostructured MOFs and their derivatives are summarized, and their corresponding prospects are also discussed.

Metal–Organic Framework (MOF)‐Derived Carbon‐Mediated Interfacial Reaction for the Synthesis of CeO2−MnO2 Catalysts

“…Recently, metal oxides derived from metal–organic frameworks (MOFs) have attracted great attention, because the metal oxides inherit high porosity and large surface area from the MOFs after pyrolysis . Small cavities and open channels within MOF‐derived metal oxides favor the mass transfer of reactant species.…”
