“…[48] They chose Zr-PCN-222 (a zirconium-porphyrinic MOF, PCN: porous coordination network) as MOF substrate, in which the porphyrin ligand could serve as tetrakis coordination sites to stabilize the single atoms. Our group has reported a benign method to acquire Pt/Ir SAs implanted hollow nanotube MOF (HNTM).…”

Their highly functional nature has endowed metal-organic frameworks (MOFs) with diverse applications. On this basis, a higher demand has been proposed for the preparation of novel-structured MOFs. Hollow MOFs have been intensively studied and exhibited versatile properties, and among the various methods, secondary-component incorporation has been proved promising in the design and preparation of complex structures with requisite properties. Herein, the synthesis and applications of secondary component incorporated MOFs and their derivatives are systematically reviewed. Two main methodologies, preincorporation and postmodification, are discussed in detail, and the role of the secondary component is demonstrated. Based on these introductions, the applications of those materials, including chemical catalysis, electrocatalysis, and energy storage applications, are summarized. Finally, a personal outlook for the future opportunities and challenges in this field is given.

“…The former was able to preferentially enter the hydrophilic pores of the MOFs, and thus deposition of metal NPs on the exterior surface was minimized after undergoing the reduction step. In another significant work, Wang's group had successfully carried out the incorporation of catalytic active single atoms into MOFs . The Zr‐based MOFs contain porphyrin units which serve as well‐defined anchoring sites for single atom catalysts (Figure b).…”

“…One possible reason could be the presence of higher defect sites in the 2D MOF samples, which could affect the metal‐support interactions or change the catalytic mechanism. Apart from the incorporation of metal NPs, Wang's group recently reported the synthesis of catalytic active Zr‐MOF‐supported single atoms for photocatalytic hydrogen production . Furthermore, the MOF‐composites could be designed to possess hollow structures with shell thickness of approximately 100 nm.…”

In recent years, metal‐organic frameworks (MOFs) have gained tremendous attention as an emerging class of functional materials for the field of heterogeneous catalysis. In particular, low‐dimensionality of these material‐platforms can be singled out as an important structural parameter that endows unique or new functionalities and thus enables improved catalytic performance. Herein, firstly, this Review summarizes important development of the synthetic preparation strategies of low‐dimensional MOFs and their related composites. Next, effects of dimensionality on different catalytic roles of MOF platforms are highlighted and discussed. For instance, MOFs have been employed directly as heterogeneous catalysts, in which catalytic reactions take place within their pristine or deliberately created pores. Exploiting on the ordered pore structures, MOFs have also been integrated into reactor‐like catalysts to act as a membrane for selective catalysis. MOFs have also demonstrated to be unique support materials for other catalyst components, of which enhancement in stability and catalytic performance have been addressed. Lastly, MOFs have also been extensively utilized as a sacrificial template to derive highly porous and catalytic active nanomaterials. On the basis of our personal perspectives, some future research directions are suggested in this review in order to further advance this class of emerging catalysts.

“…Moreover, the agglomeration of Pt atoms into large Pt nanoparticles was not observed after four catalytic runs and the recovered Al‐TCPP‐Pt could be reused without significant deterioration in the catalytic activity. At about the same time, Wang and co‐workers synthesized a series of noble‐metal (Ir, Pt, Ru, Au, Pd) single atoms immobilized in MOFs with a hollow nanotube structure . The bimetallic Pt–Ir single‐atom‐immobilized MOF displayed excellent photocatalytic activity due to a unique structure, fast mass transformation, and improved charge separation efficiency.…”

Single-site photocatalysts generally display excellent photocatalytic activity and considerably high stability compared with homogeneous catalytic systems. A rational structural design of single-site photocatalysts with isolated, uniform, and spatially separated active sites in a given solid is of prime importance to achieve high photocatalytic activity. Intense attention has been focused on the design and fabrication of single-site photocatalysts by using porous materials as a platform. Metal-organic frameworks (MOFs) have great potential in the design and fabrication of single-site photocatalysts due to their remarkable porosity, ultrahigh surface area, extraordinary tailorability, and significant diversity. MOFs can provide an abundant number of binding sites to anchor active sites, which results in a significant enhancement in photocatalytic performance. In this focus review, the development of single-site MOF photocatalysts that perform important and challenging chemical redox reactions, such as photocatalytic H production, photocatalytic CO conversion, and organic transformations, is summarized thoroughly. Successful strategies for the construction of single-site MOF photocatalysts are summarized and major challenges in their practical applications are noted.
