“…Different from traditional photocatalysts, MOFs show some distinct photocatalytic properties arising from metal node, organic linker or both . To effectively separate electron and hole generated by light irradiation and improve the catalytic efficiency, MOFs are promising hosts for encapsulating electron acceptors and semiconductive NPs, such as metals, metal oxides, POMs, photoactive metal complexes or dyes, in which they will generate intriguing synergy functions compared with single counterparts.…”

Beyond conventional porous materials, metal–organic frameworks (MOFs) have aroused great interest in the construction of nanocatalysts with the characteristics of catalytically active nanoparticles (NPs) confined into the cavities/channels of MOFs or surrounded by MOFs. The advantages of adopting MOFs as the encapsulating matrix are multifold: uniform and long‐range ordered cavities can effectively promote the mass transfer and diffusion of substrates and products, while the diverse metal nodes and tunable organic linkers may enable outstanding synergy functions with the encapsulated active NPs. Herein, some key issues related to MOFs for catalysis are discussed. Then, state‐of‐the art progress in the encapsulation of catalytically active NPs by MOFs as well as their synergy functions for enhanced catalytic performance in the fields of thermo‐, photo‐, and electrocatalysis are summarized. Notably, encapsulation‐structured nanocatalysts exhibit distinct advantages over conventional supported catalysts, especially in terms of the catalytic selectivity and stability. Finally, challenges and future developments in MOF‐based encapsulation‐structured nanocatalysts are proposed. The aim is to deliver better insight into the design of well‐defined nanocatalysts with atomically accurate structures and high performance in challenging reactions.

Metal-organic frameworks (MOFs), a new class of crystalline porous organic-inorganic hybrid materials, have recently attracted increasing interest in the field of energy storage and conversion. Herein, recent progress of MOFs and MOF composites for energy storage and conversion applications, including photochemical and electrochemical fuel production (hydrogen production and CO reduction), water oxidation, supercapacitors, and Li-based batteries (Li-ion, Li-S, and Li-O batteries), is summarized. Typical development strategies (e.g., incorporation of active components, design of smart morphologies, and judicious selection of organic linkers and metal nodes) of MOFs and MOF composites for particular energy storage and conversion applications are highlighted. A broad overview of recent progress is provided, which will hopefully promote the future development of MOFs and MOF composites for advanced energy storage and conversion applications.

“…The water oxidation active site was determined to be (bpydc)Ir(H 2 O) 2 XCl (X = formate or acetate group) after oxidation of the Cp* rings via Ce 4+ . Matsuoka's group investigated whether the uniformly dispersed Fe oxo‐nodes in MIL‐101(Fe) enhanced the interactions with the reactants, which would decrease the carrier migration length during photocatalysis . Using AgNO 3 as a sacrificial electron donor, MIL‐101(Fe) promoted photocatalytic water oxidation at a higher rate than bulk Fe 2 O 3 under visible‐light irradiation .…”

Metal-organic frameworks (MOFs) are intriguing platforms with multiple functionalities. Additional functionalization of MOFs generates novel materials for various applications. Here, three main topics are examined regarding the functionalization of MOFs for use as photoactive materials. The first is chemical approaches for postsynthetic modification of the metal clusters and organic linkers in MOFs; that is, sites on pore surfaces and chemical trapping of photoactive moieties within the pores, which create materials with chemical functionalities for water splitting and CO reduction by light. The second topic focuses on the functionalization of MOFs for photochemical response and the versatile applications of such materials. State-of-the-art research on functionalizing MOFs through photochemical reactions on the pore surface and within the pores as guests is also summarized. The third topic introduces the functionalization of MOFs for photofunctional materials, including photoluminescent tuning and integration, photoluminescent LED devices and barcodes, and photophysical applications for chemical sensing. Finally, conclusions and perspectives on the fields are given.
